1600 Hello! For the last two years I have been experiencing small red itchy bumps from my waist up, 1-2 a day. I had an exterminator here yesterday, and he treated the whole house. Afterwards, I came home and washed the pillow cases just to remove any residue from the insecticide, although he said it was safe. After washing, I shook them out. I found about 10 of these tiny insects. They are just over a millimeter long and amber in color. I think they are book lice (psocids) as I had a stack of books next to the bed that have been there for about two years, but the research I did says they don't bite but people can have an allergic reaction to them. I still got bites after the first treatment, but I will have the house treated again. I just want to know what this little pest is. Consequently, my husband has no symptoms, but my bites itch something fierce.
Thanks for any information you can provide. Sincerely, Carol
Although the image is fuzzy, it does appear to be a booklouse (Psocoptera: Liposcelidae). They definitely would not be responsible for any bites, and allergic reactions attributed to them have been respiratory rather than dermatological in nature - see http://www.indianexpress.com/res/web/pIe/ie/daily/19991029/ige29035.html for an example. Unfortunately, treating your house with pesticides without knowing what exactly is causing your symptoms may be an exercise in futility. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1599 Could you please help me identify this bug. I found him in my front yard in Houston, Texas where it's still 85 degrees Fahrenheit in November. This photo shows him against a blade of grass so you can tell he is very small. Sabra.
This is a lovely photo of a green lacewing (Neuroptera: Chrysopidae). They and their larvae are voracious predators on small soft-bodied arthropods such as aphids, and thus considered beneficial. See http://www.ipm.ucdavis.edu/PMG/NE/green_lacewing.html for more information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1598 Hi, I live in an older home in Toronto and we recently found a couple of these bugs near the seams on our mattress! We were actually in the process of getting a new bed at the time when they were noticed. They are about 2-5mm in length. We have never had any bites we were aware of nor was there any evidence of dark feces stains on the mattress. We had an exterminator come who felt confidant they were NOT bed bugs. He thought they may be a larval form of a sowbug/pill bug or something similar. He did spray the baseboards with a general insecticide. I have since found them on the carpet in the bedroom. I'm wondering if they might be larvae of the carpet beetle? Torin. University of Toronto

These are larvae of carpet/furniture beetles (Coleoptera: Dermestidae) in the genus Anthrenus. See http://ohioline.osu.edu/hyg-fact/2000/2103.html for a fact sheet that includes control recommendations. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1597 Hello, We live in a small town outside of Houston, Texas. My husband found this wormlike creature while cleaning out his barbecue pit yesterday morning. It has white fur, like a mammal, and a red/dark orange grooved ridge on its back. We couldn't tell which end was its head, and it writhed along the grill plate shown, as if it was a worm. My husband knocked it to the ground, and it curled up, then rolled over and continued scooting along the ground. I have never seen anything like this, and I'm a little worried if it's harmful or not. Thanks for any insight you might be able to offer. Best, Amanda
This is a flannel moth caterpillar (Lepidoptera: Megalopygidae) in the genus Megalopyge. Specifically, it appears to be a southern puss moth caterpillar (Megalopyge opercularis), sometimes known as the asp moth caterpillar or puss moth caterpillar - see http://www.bugsinthenews.com/puss_caterpillar_092602.htm for much more information on this species. Beware - its soft fuzzy appearance belies the sharp venomous spines hidden beneath - touching these caterpillars is not advised! Ed Saugstad, retired entomologist; Sinks Grove, WV.

1596 Hi, We live in Southern California and found this in our bathroom sink. It moved kind of like a maggot. Can you please tell me what this is. Thank You, Cindi

This specimen is too badly damaged to be certain, but the stubs of what appear to be three terminal abdominal appendages lead me to believe that it could be a bristletail (order Thysanura) such as a silverfish or firebrat - see http://www.ucmp.berkeley.edu/arthropoda/uniramia/thysanura.html Ed Saugstad, retired entomologist; Sinks Grove, WV

1595 Good Day: We discovered this "little" wonder bug crawling along the family room wall, just down by the baseboards. The room is clean with relatively new carpeting and is used regularly. I would suspect that it recently entered the room. The bug is a tan coloured "thing" with black stripes running horizontally across it's torso and legs. the body is 1 inch long and the longest legs (at the back) are 3/4 inch long. The body is 1/4 inch wide across. there are small spikes at the joints of the legs and it has a long whip like antenna thing sticking out the back. it moves at a reasonable pace until it is scared, then it takes off at a pretty quick pace. If you could let us know what this thing is, whether we should be weary of it, whether it's in any way poisonous and whether it breeds like rabbits (dear God no!) we would deeply appreciate it. My two children were really freaking out when I was trying to catch it. Any information deeply appreciated as my children are dying to know what this thing is. Thank You: Chris Jenkins
This is a House Centipede. Centipedes prefer to live in damp portions of basements, closets, bathrooms, unexcavated areas under the house and beneath the bark of firewood stored indoors. They do not come up through the drain pipes. House centipedes feed on small insects, insect larvae, and on spiders. Thus they are beneficial, though most homeowners take a different point-of-view and consider them a nuisance. Technically, the house centipede could bite, but it is considered harmless to people. For more information see this web page: http://www.pestcontrolcanada.com/INSECTS/Centipedes.htm

1594 Can you advise what kind of spider this appears to be. We live in the Brooks area of south eastern Alberta. I look forward to your response. Regards, Rob
This is a female orb-weaving spider (family Araneidae); specifically, it is the banded argiope/banded garden spider Argiope trifasciata - see http://www.photoquest.com/dsoto/twentythree.shtml for an image.
This species appears to be fairly common in prairie areas of Alberta - see
http://www.canadianarachnology.org/data/canada_spiders/SpecimenLists2.asp?SpeciesCode=15415 for collection records. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1593 I would like to identify this bee. My son was stung and he had an anaphylactic reaction. It must be a type of honey bee since it lost its stinger, but it does not look like the pictures of honey bees. The nest was inside a rotting log in a woodpile in Mississauga Ontario. I have attached a picture of a bee that was still slightly alive, and the nest it came from. Thanks. Paul

This is not a bee, but a social wasp (Hymenoptera: Vespidae). Sensitive people can have anaphylactic reactions to their venom - see http://ohioline.osu.edu/hyg-fact/2000/2076.html. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1592 What is this, it was 2-3 inches long, flew onto my brother in laws leg in the evening in the Okanagan valley in British Columbia, between Peachland and Summerland, near the lake. Robert.
This is a giant water bug (Hemiptera: Belostomatidae). Also known as toe-biters and electric light bugs, they are voracious predators on other aquatic life. They are excellent fliers, and often can be found at quite some distance from any water source. They are capable of delivering quite a painful ‘bite’ if mishandled. See nos. 1546, 1513, 1498, 1457, and 1378 for other examples. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1591 Hello Friends. Hoping to find some answers as to what this insect is and if it should be of concern. It was found outside mid-October in the Spokane, Washington area. North slope in a mixed mesic forest at 3,000 feet. There seemed to be a hatch of them as I had about 12 on me after walking outside for 10 minutes. My dog also had a bunch on her. They were slow moving but very clingy. This is not the first time I've seen them - I believe I have seen them in past years around the same time. Any help would be much appreciated. Sami
This appears to be a louse fly (Diptera: Hippoboscidae); they are ectoparasites of birds and mammals. They can be winged (see http://cc.oulu.fi/~lcervi/lcervi_lajikuva.jpg) or wingless (see http://www.myrmecos.net/insects/Hippoboscid1.JPG). It appears to be quite unusual for these to be found off their host, especially in any numbers as you seem to have encountered. Females produce only one offspring at a time, with the larva developing internally - see http://creatures.ifas.ufl.edu/livestock/deer_ked.htm. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1590 I found this spider last night outside our door in Vancouver BC. It hadn’t been there long – maybe since the morning. We’re letting it stay there for now and we’ll make our next move when we find out exactly what type of spider it is. Hoping it will stay outside and not make the move inside. Thanks! Christine

This is a female orb-weaving spider (family Araneidae); likely in the genus Araneus. They are completely harmless to humans, and it should not make any move to come indoors. If you scroll down this site starting at no. 1586, you will see many other examples of this family of spiders. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1589 We found these in our cabin at Thunder Lake Alberta. They seem to migrate to water as every time when we return to the cabin, usually every weekend or two We find several in the toilet and in the tub. They are usually spotted in the baseboards and then they proceed to crawl to the ceiling where they will actually crawl until they fall off. When accosted they “turtle” and are easy to pick up and throw in the trash. They do not seem to be in the dry goods but are in all the walls. I pick up between 10 and 15 a day. Our basement is a dirt root cellar and it is a bungalow. I have seen traces in the root cellar but it is a crawl space and rather uncomfortable to get into. My wife thinks they are cute so therefore harmless. I believe they are short snouted weevils. Dwaine
This is indeed a short-snouted weevil (subfamily Entiminae), such as the strawberry root weevil (Otiorhynchus ovatus). These weevils often enter homes at the onset of cold weather in the autumn - see http://weaselhead.org/profile/index.php?s=1435 for an image and more details. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1588 Hello friends, I found these two specimens in my backyard here in Winnipeg, MB. Just wondering what they are. V. Pearase
This appears to be a fruit fly (Diptera: Tephritidae), bearing a strong resemblance to the sunflower maggot, Strauzia longipennis - see http://www.cirrusimage.com/fly_fruit_Strauzia.htm. These flies should not be confused with those in the family Drosophilidae, which also sometimes are called fruit flies (they more properly are termed pomace flies or vinegar flies). Ed Saugstad, retired entomologist; Sinks Grove, WV.

1587 My husband & I found this on our carport one night this summer sitting on an empty box. We live in central Illinois & neither of us has ever seen one of these before. It was about 5 inches long & about 3/4 inch thick. The colors in the photo are pretty accurate. It was a bright green with yellow bumps towards what I think was the front, It had groups of what looked like 5-10 bright blue hairs running along both sides of its body. We're dying to know what it was! Thanks, Sara Carter
This is a larva of a cecropia moth (Hyalophora cecropia; Lepidoptera: Saturniidae), arguably the largest moth in North America. See http://www.ivyhall.district96.k12.il.us/4TH/KKHP/1insects/cecropia.htm l for detailed information on this fascinating insect. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1586 Could you please tell us something about this beautiful spider which has been living on our patio on one of the potted plants. We have been taking many photos of it and it doesn't seem to mind one bit. We are worried that it might be dying, however, as today it is seems not as active. The back end seems to be changing to a solid tan colour. Thank you for your assistance. Al Grant

This is a female orb-weaving spider (family Araneidae) in the genus Argiope - see http://www.cirrusimage.com/Spider/argiope_underside2.jpg for an image. Your spider is near the end of its life span; it shortly will construct an egg case of tough silk
(see http://www.geocities.com/tom.allen/spider_1999-09-17/argiope.htm ), lay its eggs in it, and soon thereafter shuffle off this mortal coil. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1585 These have started to appear about one per day in my bathroom. They do not scatter. This one was unfazed by several flash photos taken at about an 8 inch range. Some have been maybe up to 25% larger. How to get rid of them?
This is a cockroach in the genus Periplaneta; most likely the American cockroach, Periplaneta americana; Blattodea: Blattidae). See http://www.entomology.cornell.edu/Extension/DiagnosticLab/IDLFS/Cockroaches/images/1435178.jpg for an image and http://edis.ifas.ufl.edu/IG082 for detailed information on control methods. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1584 Can you please tell me what kind of spider this it? I caught him/her in the large margarine container you see in the picture, so you can judge the size of it from that. I have many spiders outside my house but i have never seen one like this before. I scooped it up off my living room floor this past spring, at my home in Victoria B.C., Canada. Some insight please! Mark

This appears to be a woodlouse spider (Dysdera crocata; see http://www.uksafari.com/woodlousespiders.htm ). This spider is widely distributed in the northern hemisphere; it preys primarily on woodlice (Crustacea: Isopoda), also known as sowbugs, pill bugs, or roly polys. Their overly large fangs easily penetrate the tough exoskeleton of its prey. They can deliver a painful bite if mishandled, but do not appear to be particularly dangerous. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1583 I'm really interested in knowing what kind of insect this is. I can't seem to find it anywhere. When it is stretched out, is about 2-3" long. You can see a long black antennae type thing that kind of circles around its body, then goes into the hole in the tree. Now, this tree is starting to die, and were not sure if it's due to these insects. All suggestions would be much appreciated. Thank You, Josh

This is an ichneumon wasp (Hymenoptera: Ichneumonidae) in the genus Megarhyssa; see nos 1531 and 1437 for other examples, and http://insects.ummz.lsa.umich.edu/Images/Hymenoptera/megarhyssa.html for more information. It is not responsible for your tree’s decline, as it is parasitic on the larvae of wasps in another family (Siricidae) that bore in the wood. Likewise, those larvae usually are found in the wood of trees that already are dead or dying. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1582 Hi, I live in southwest Washington state and been seeing these beetle-like bugs for a while now. They are always around my flowerbed along the house. The attached pictures show the bugs on the side of my house. I usually see them in groups of a dozen or so in the afternoon. I would like to know if they are harmful to the house or to my family or pets. Thanks, Cindy in Shelton

This is a bordered plant bug (Largus succinctus; Hemiptera: Largidae). Like boxelder bugs, they appear to be more of a nuisance pest than an economic one. See http://davesgarden.com/guides/bf/go/21/ for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1581 I found this guy in the middle of the living room in my Tulsa, Oklahoma townhouse. Weather outside is usual November weather, generally between 50-70 degrees. I honestly can't tell whether he's eating another small insect, or whether he has an extra set of small antennae on his head (don't have a magnifying glass). He doesn't appear to be in too good of shape, as he didn't crawl away when I was trying to focus the camera. Look familiar to anyone? Thanks! April

This appears to be a ground beetle (Coleoptera: Carabidae); the vast majority of these beetles are general predators on other small arthropods. From the angle that the photo was taken, the antennae likely cannot be seen clearly; what appear to be short antennae likely are its maxillary palps. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1580 This is the larvae of some sort of wood boring pest. I found it (with others like it) eating my baseboards in my house. I live in Pismo Beach California which is on the central coast in San Luis Obispo County. After noticing in exit holes and frass I removed the baseboard and when I tapped on it the little buggers emerged. The one in the photo is dead (from a spray treatment I used). Sorry I wasn't able to get a better picture. Hope someone can tell me what it is for sure. My best guess is that it might be a powder post beetle. Thanks. Les
This does not appear to be a powder post beetle larva (they usually are somewhat C-shaped), but could be a drywood termite (Isoptera: Kalotermitidae). Activity of these termites often is detected by finding piles of frass near holes in wood (powderpost beetles usually do not routinely eject frass from their feeding tunnels, but instead pack it back in as they feed). In those that do expel frass (family Lyctidae), the frass feels like fine flour or talc, whereas drywood termite frass feels like small, hard pellets. See http://creatures.ifas.ufl.edu/urban/termites/western_drywood_termite.htm for detailed information on these termites. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1579 My sister found this bug, moth? on her snapdragons this past summer and we are curious to know what it is. She lives in Winnipeg, Manitoba. We would appreciate it's identification. Thanks, Laurie.

This is a sphinx moth (Lepidoptera: Sphingidae); specifically, it appears to be a white-lined sphinx (Hyles lineata) - see http://www.silkmoths.bizland.com/hlinelin.htm for images and much more information. Sphinx moths also may be known as hawk moths or hummingbird moths; their larvae usually are characterized by a prominent horn-like projection at the end of their abdomen; see http://nathistoc.bio.uci.edu/lepidopt/sphingid/ManducaLarva.jpg. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1578 I believe this is the underside of the spider. I live in Richmond, VA and found this guy between the railing and garden in front yard. I've noticed that I usually only see him early in the morning and nighttime. Jaycee

This is a female orb-weaving spider (family Araneidae); possibly in the genus Neoscona - see http://frank.itlab.us/sasha/araneus_cavaticus.jpg for an image. All orb weavers are harmless to humans. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1577 My mother found this bug in her house along with another one only smaller. Can anyone tell me what it is? I thought it might be in the ant family because of its head which looks like a carpenter ant, but its body has me confused. This bug has six legs and no wings. Rick from Rockford, IL.

This is a blister beetle (Coleoptera: Meloidae); likely in the genus Meloe - see http://perso.orange.fr/pechelacsariege/images/meloe.JPG for an image. Beetles in this genus have the wings greatly reduced, and when threatened, exude an oily liquid from their joints. This liquid will stain skin, and has a very unpleasant odor. Their larvae are parasitoids on bees, and in at least one species, have a very unusual means of dispersal in that after hatching, they congregate on vegetation, imitating the form of a female bee. They then climb on to any male bee that stops to investigate and get a free ride to the bee’s nest; see http://www.nature.com/nature/journal/v405/n6782/full/405035a0.html. Ed Saugstad, retired entomologist; Sinks Grove, WV.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is a flightless Blister Beetle, Meloe sp., beetle family Meloidae. They are parasitic as larvae in the nests of ground-dwelling solitary bees. Jim McClarin

1576 Many of these were swept off the floor of an older home in Burlington Ontario, Canada. They are about 1.5 mm in length and have a reflective, almost iridescent purple/blue sheen. They were collected in October 2005. Best I can figure out is they may be some kind of Springtail? Corey Lewis, Beamsville, ON
These indeed are springtails; see http://www.entomology.wisc.edu/insectid/insect_info.php?64. Authorities are divided as to whether or not they should be considered true insects. The vast majority are harmless scavengers, but a few species can be pests on tender vegetation; see http://www.discoverlife.org/20/q?search=Sminthurus+viridis . Ed Saugstad, retired entomologist; Sinks Grove, WV.

1575 Here it is the end of October and we never thought we’d be bothered by bugs while camping… hundreds of them …. at 20 mile Bay at Harrison Lake, British Columbia. We’ve come away with a few bites and they are swollen, red and itchy. We assume they’re from these bugs but that’s not a certainty, I suppose. We’d love to know what these critters are. - Dave and Maureen
There are a number of biting flies in British Columbia that can be serious nuisances. Unfortunately, I cannot tell for certain what you have photographed. It might be a deer fly or small horse fly (Diptera: Tabanidae); see http://eny3005.ifas.ufl.edu/lab1/Diptera/Tabanid.htm and http://insects.tamu.edu/extension/youth/bug/bug142.html for some images. Other problem flies (besides mosquitoes) include biting midges (Ceratopogonidae; see http://i.pbase.com/u36/holopain/large/32189277.Ceratopogonidae.jpg ) and black flies (Simuliidae; see http://www.uku.fi/~holopain/stt/Simuliidae1.jpg ), but your specimen definitely is neither of those.

1574 Hi, Recently our whole family (my husband, both my sons & myself) suffered very itchy red spots on our body, like on our stomach, arms, backs and thighs (one of my sons even got it on his face). Doc. (dermatologist) diagnosed it as bug bites, not scabies, not allergic. It was 3am, and I found these two bugs on my mattress (next to me who was sleeping!). Are they bedbugs? I showed them to my doc, he said it wasn't bed bugs but he can't tell what. I'm kind of sure they are bedbugs because last week I went abroad for 5days and suffer no new itchy red spots. When I came back home, the next morning my family & I got new itchy red spots again. Please help. The itch is driving us crazy. Thanks. Helen
Whatever these are, they definitely are not bed bugs - see http://www.ca.uky.edu/entomology/entfacts/ef636.asp. However, the images are not clear enough to offer a definitive identification. They may be mites or even spider beetles -
see http://www.galerie-insecte.org/galerie/image/dos12/big/insecte.jpg.jpg . It also may be that the occurrence of these creatures and the bite symptoms are coincidental. Diagnosing arthropod bites without actually catching the culprit(s) in the act can be quite problematic.
See http://www.ca.uky.edu/agc/pubs/ent/ent58/ent58.pdf for more information on this subject. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Hi Ed, following your suggestion about the possibility of mites, I found this website
http://www.the-piedpiper.co.uk/th5i.htm#birdmite. I found its BIRDMITE pic to have similar body shape and proportion of the head vs body with the bug I found. Furthermore, the long sharp front-leg on the sides of its head is also similar with the pic of this http://medent.usyd.edu.au/fact/birdmite.html. Do you think now we can say it’s bird mite definitely? There is this scary website about birdmites (birdmites.org) that says despite popular information that birdmites can’t live away from its host (birds), birdmites can parasite on humans forever, do you think is it true? Helen.
~~~~~~~~~~~~~~~~~~~~~~~~~~~

Although mites definitely are a possibility in this case, there is something about the image that keeps me from being confident about identifying it as such. If at all possible, could you take some more close-up photos that would more clearly show its legs and underside? As for bird mites becoming permanently parasitic on humans, I would be extremely skeptical to say the least - there is a lot of misleading if not downright erroneous ‘anecdotal’ medical information on the web. Ed Saugstad, retired entomologist; Sinks Grove, WV. ~~~~~~~~~~~~~~~~~~~~~~~~~~~

After viewing the photo’s of item # 1574, definitely not bedbugs, these match a similar mite infestation at our Milton West Virginia home. No bites to report. After further investigation, I think they may be “Clover Mites”?? See http://www.ces.ncsu.edu/depts/ent/notes/mites.htm . Donald L

1573 This guy was found in my kitchen, which I am guessing snuck through a hole where the air conditioner is in the window. It has very distinct markings...black and white stripes on his head, a brown smooth body with 2 black lines running from the tip of his abdomen to the back end. The underside of his abdomen is more of a beige colour, also with 2 black lines running to both ends. I've never seen a spider with these kinds of markings before.
I thought of a wolf spider at first, but this guy's body isn't hairy like the others and the markings are different. His abdomen isn't as flat as most either, its more round. Is there a similar species that isn't so hairy? Sue Judges. Pembroke, Ontario.
This is a grass/funnel web spider (family Agelenidae, possibly in the genus Agelenopsis - see http://www.wildutah.us/spdr_010906drpr14.jpg for an image. Agelenids can be distinguished from wolf spiders (family Lycosidae) by the presence of the long spinnerets seen at the end of the abdomen, and by the lack of enlarged front median eyes. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1572 We had some juniper trees felled this year and slabed for benches. They are curing in my shop. This summer these fellows started to fly in the shop. We live in Central Oregon, USA. Thanks for any help. Randi
This appears to be a horntail (Hymenoptera: Siricidae). Their larvae usually bore in the wood of trees that already are in decline or already dead. Thus, they seldom are responsible in themselves for tree death, but if numerous, they can adversely affect lumber quality. In turn, their larvae often are parasitized by large ichneumon wasps in the genus Megarhyssa - see http://insects.ummz.lsa.umich.edu/Images/Hymenoptera/megarhyssa.html. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1571 We live in northeast Iowa, in a very, very small town surrounded by miles and miles of corn fields. We found this thing in our yard in Sept 2007. It measured 4" long 1"wide. What is it? Only found 1, never saw any others, and hope not to. Thank you.. Brenda
This appears to be a mature caterpillar of the Imperial moth (Eacles imperialis; Lepidoptera: Saturniidae); see no. 1543 for another example and http://pick5.pick.uga.edu/mp/20q?search=Eacles+imperialis for images of larvae and an adult moth. Although they feed on a variety of foliage, including oaks, maples, sassafras, sweetgum, and pines, they seldom are numerous enough to cause real damage, and appear to be on the decline in the northern areas of their range.

1570 Hi, I live in Montreal, Québec and I found this mother in my basement. She impressed me quite a bit with her 58 babies. I have seen this specie quite frequently in and around the house and don't think they cause any harm. I thought it was a daddy long legs but there body usually looks like one round ball while this one clearly has a separated abdomen and head. Please let me know what specie this is. Thanks for the info - tiben26
This spider is in the family Pholcidae; namely, it appears to be the cosmopolitan species Pholcus phalangioides - see http://www.xs4all.nl/~ednieuw/Spiders/Pholcidae/Pholcidae.htm for much more information. Commonly called ‘cellar spiders,’ they also can be known as ‘daddy long legs,’ but they should not be confused with opilionids (see , relatives of spiders also known by the same common name as well as by ‘harvestmen’ - see http://www.xs4all.nl/~ednieuw/Spiders/Opiliones/Opiliones.htm. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1569 Hi, I've been looking online to find out what kinda insect this is, it looks like a REALLY BIG mosquito, I'm hoping I'm wrong and it's harmless. I almost had a panic attack in front of my 2 little kids before when son found it in the bathroom with us. Please let me know what this is, I see them all the time where I live, Staten Island, NY. Thanks so much for your help! -Norma
This is a crane fly (Diptera: Tipulidae). They often are mistaken for giant mosquitoes, but they do not bite and are entirely harmless to humans. See no. 1562 for another example. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1568 I live in Staten Island, NY. I have a huge problem with small ants in my house, especially my basement. I noticed them when I tried to do some gardening and then they appeared in the house. Today I went outside and noticed them on the stems of some lilies that I had to cut down. When I removed the stems I saw these small bugs and I have no idea what they are. The are extremely small and hard to photograph. I put it on a paper plate and zoomed in as close as I could. the stick in the picture is smaller then the width of my finger, under an inch. I hope someone can help. Shari
This is an aphid (Homoptera: Aphididae). Sometimes called ‘plant lice,’ aphids feed on the sap of plants. Some species of ants have an intimate association with aphids in that they seem to ‘farm’ them like domestic cattle, feeding on the honeydew secreted by the aphids. For more insight on this behavior,

1567 I found this spider in my backyard in late August/early September right outside of my backyard door in a corner. It was unlike any other usual spider you would probably find in a backyard of a townhouse in the middle of Mississauga, Ontario. Thanks! Julia

This is another female orb-weaving spider (family Araneidae); likely in the genus Araneus - see http://perso.wanadoo.es/albanell/blava/aracni/Araneus sp 3.JPG for a ventral view. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1566 This spider was in my friends garage in Winnipeg Manitoba Canada. It was August of 2007 and the spider was about the size of a dime. That's about the only info I have so any info would be great! Hugh.

This is a female orb-weaving spider (family Araneidae); likely in the genus Araneus - see http://www.cirrusimage.com/spider_cat_face.htm for an image and no. 1540 for another example. All are harmless to humans. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1565 They are everywhere in my backyard usually in large clusters, what are they? Tiff

These are boxelder bugs (Boisea spp.; Hemiptera: Rhopalidae) - see no. 1551 for another example. Essentially harmless, they can become nuisance pests when they congregate in large numbers on or near homes.

1564 Hey there. I found this in the insulation of my attic. It is cellulose insulation, and I only saw one. I live in Calgary. Can you help me out? Sorry about the pic, it was still alive, and can actually move pretty quick. Thanks a lot. Stuart.

This is a beetle larva, but the image is too fuzzy to say much more. However, it does not appear to be any of those species that can be serious household pests. It may be in the superfamily Tenebrionoidea. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1563 So far I have found two of these little critters in my bedroom in Northern California. I tried to figure out what they are on my own but am left in the dark. Is this the dreaded C-word? (Cockroach??!) Should I be worried about an invasion while I am sleeping? Thanks, Dianna
This is a leaf-footed bug (Hemiptera: Coreidae); possibly the western conifer seed bug (Leptoglossus occidentalis); see no. 1559 and http://www.forestry.ubc.ca/fetch21/FRST308/lab2/leptoglossus_occidentalis/leaf.html . Ed Saugstad, retired entomologist; Sinks Grove, WV.

1562 This lovely insect was found in September, 2007 on the side of a cottage in the Quebec Laurentians. Hope someone can identify it. Andre

This is a crane fly (Diptera: Tipulidae); specifically, it appears to be a giant eastern crane fly, Pedicia albivitta -
see http://pick5.pick.uga.edu/mp/20p?see=I_NAT1834&res=640 for an image. Crane flies are in the same subfamily as mosquitoes (and often are mistaken for giant mosquitoes), but they do not bite and are completely harmless to humans. Their larvae (often called ‘leatherjackets’ because of their tough cuticle) live primarily in damp/subaquatic environments; a few species can be turf pests, causing damage by feeding on grass roots. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1561 Hello: We found this bug, and a dead one similar to it, beside our daughter's crib. Specifically, it was crawling out of the baseboard underneath the nightlight in late evening. We were looking because she has received three bites to the abdomen over the last 4 weeks. We have had our place inspected for bed bugs and there was "no evidence" of the critters, save for the pictured sample that "may be an early nymph." A microbiologist at the hospital stated "it doesn't look like any bedbug I have ever seen." Any ideas on what this is? Thanks and best, Simon
This is a larva of a dermestid beetle (Coleoptera: Dermestidae); likely in the genus Anthrenus. It would not be responsible for any ‘bug bites.’ These insects feed on a wide variety of organic substances, primarily of animal origin, including wool, silk, fur, hair, leather, and accumulations of dead insects. Occasionally, they may become pantry pests as well.

1560 Anyone know what kind of spider this is..? Found in Springhill , Nova Scotia , Canada on a clothes pole in a web...date is October 22, 2007. Thanks. Ron Arseneault

This is a female Argiope aurantia, an orb-weaving spider (family Araneide). These spiders usually attract attention in late summer/autumn when the females reach full size. They are all harmless to humans, and there are many similar examples on this site, beginning with no. 1558. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1559 Date: October 23, 2007. Location: North Vancouver, Burnaby. Current conditions: recent heavy rains. Unusually wet summer. Our little visitor was found indoors, may have flown out of a air vent. Size: 2cm x 3cm. Is this a pest that we should take care of asap, or are they harmless? Thanks. Kent

This is a leaf-footed bug (Hemiptera: Coreidae), such as the western conifer seed bug (Leptoglossus occidentalis); see http://www.forestry.ubc.ca/fetch21/FRST308/lab2/leptoglossus_occidentalis/leaf.html. Coreids often enter homes in autumn, in search of overwintering shelter. If you scroll down this site, you will see many similar examples, beginning with no. 1532. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1558 Hi, we have this 4 inch visitor in our window at work in Oklahoma City. Everyone loves passing by him to see if he's moved or done something new overnight. I even used his photo for my Halloween party invitations. We think he might be a Banana spider. Do you know for sure? Thanks, Shannon Cornman, Photographer , Oklahoma Gazette
This is a female orb-weaving spider (family Araneidae) in the genus Argiope; if you scroll down through the images on this site starting with no. 1525, you will find many similar examples. Although the females can reach quite an impressive size, they all are harmless to humans. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1557 What is this spider. Jeff & Kelly.
This appears to be a male orb-weaving spider (family Araneidae) in the genus Argiope; see http://www.pbase.com/tmurray74/image/32785404 for an image. They are much smaller than the females in the genus; see no. 1558 for an example. Ed Saugstad, retired entomologist; Sinks Grove, WV

1556 We live in Prince Edward County, Ontario & have hot dry weather for the past week. We have an infestation of these tiny bugs in our bathroom. They are all over the floor & in the tub. They jump about 4" when we try to squish them. Once squished they leave a dark, blue-black smudge as if they have an ink in them.

These are springtails (order Collembola); authorities differ as to whether they should be considered true insects. They require a moist environment in which to thrive, so finding them in a bathroom does not come as a surprise. Although harmless, they can be nuisance pests when they occur in large numbers. The best control is to eliminate as many sources of unnecessary moisture as possible in and around the home. See http://www.cals.ncsu.edu/course/ent425/compendium/collem.html for more information. Ed Saugstad, retired entomologist; Sinks Grove, WV

1555 I found this dead insect on the side walk in front of our home in Georgetown, Ontario, Canada. It was in perfect shape but it had turned a gray-white colour on it's under side. Due to it's size, I placed a quarter beside it in the photo's. It is quite large. I am very curious to find out what it is and a little more about it.
With Thanks. Gale

This is a cicada (Homoptera: Cicadidae), likely in the genus Tibicen. These cicadas have shorter life cycles (one to ten years) than those of the famous periodical cicadas (Magicicada spp.). Tibicen spp. often are called ‘dog day cicadas’ because they usually emerge during late summer. See http://webs.lander.edu/rsfox/invertebrates/tibicen.html for much more information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1554 I took this picture recently near Ste. Anne, MB. Any help in identifying the bug would be greatly appreciated. Larry Trush

This is a southern corn rootworm (Diabrotica undecimpunctata howardi). Also known as the spotted cucumber beetle, it is a common pest in gardens -
see http://insects.tamu.edu/extension/answers/identify/soil/southern_corn_rootworm.html for more information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1553 Hi there, I found this Pest in my milk powder, could you help me to identify as what it is? The enclosed picture was taken under the microscope; the size of the Pest is about 1.5mm only. Thanks for your help! EK
There could be two different types of insect here. The larger specimens (on the left of the photo) could be beetle larvae, such as dermestids that have been denuded of the characteristic body hairs, but the smaller ones look more like larvae in the orders Diptera or Hymenoptera. Regardless of their identity, control recommendations for pantry pests are quite similar, concentrating on removal and disposal of all infested material followed by storage of infestable materials in insect-proof containers - see http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7452.html for detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1552 Hi, I live in Ontario, Canada and I caught this rodent in a mouse trap in my yard. It doesn't look like your typical field mouse and it's not a vole or a small mole. Can someone please identify this rodent. Many Thanks. Nicholas

This looks like it could be a shrew. If it is, it is actually not considered to be a rodent! Shrews are related to moles and hedgehogs, and are classified as insectivores. Catherine
This is a shrew, a tiny but voracious predator. They are only distantly related to mice, being in the order Insectivora rather than Rodentia. There are several species that can occur in eastern Canada (see http://www.ontarionature.org/pdf/mammal_atlas_shrews.pdf); the commonest of which likely is the masked shrew (Sorex cinereus), also known as the common shrew or cinereus shrew - see http://www.mnh.si.edu/mna/image_info.cfm?species_id=320 .Ed Saugstad, retired entomologist; Sinks Grove, WV.

1551 Hi. I found a swarm of these red bugs in my garden in Niagara Falls today. They are huddling in groups and crawling all over the place, in the grass, on concrete patio stones and on shrub trunks. What are they and are they harmful? Hilary, Niagara Falls, ON
These are nymphs of the eastern boxelder bug (Boisea trivittata [formerly Leptocoris trivittatus]; Hemiptera: Rhopalidae). These bugs often are considered nuisance pests when the congregate in large numbers on tree trunks and on or around buildings. However, they appear to do little real damage.

1550 Found on the wall near my front door. Just stayed there while I took pics. Went back and it was gone. Irving.
This is a plant bug (Hemiptera: Miridae), specifically, it appears to be a tarnished plant bug (Lygus lineolaris); see http://www.uky.edu/Ag/kpn/tarplbug.jpg for an image. These bugs will feed on an extremely wide range of plant species, often causing considerable damage. See http://www.ento.psu.edu/extension/factsheets/tarnished_plant_bug.htm for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1549 Hello, We've been finding a number of these insects in different places in our townhouse - in the bathroom, kitchen (near some old spices we've since thrown away), in the laundry (washer/dryer are in the basement), and in the bedrooms. The bugs in the bedroom might be from the laundry. They're about 4mm long and move like a worm or centipede. I suspect they might be larvae because we also sometimes see black beetles in the same places. I don't have any photos of the beetles, but they're completely black and the same length but wider. Can you identify them? Thanks! Craig (in Calgary)
This appears to be a larva of the black carpet beetle (Attagenus unicolor; Coleoptera: Dermestidae) - see
http://www.pestcontrol-products.com/BlackCarpetBeetleadult_larva.jpg . They will feed on just about anything of animal origin, including wool, silk, hair, feathers, leather, furs, taxidermy specimens, or dead insects. They may also feed on cereal grain products and nut meats. You need to do a thorough search to locate everything they may be feeding on, and then take corrective actions. See http://creatures.ifas.ufl.edu/fabric/black_carpet_beetle.htm for a fact sheet that includes control recommendations. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1548 We found this bug on a job site on Vancouver island BC Canada. We were on an Indian reserved painting 6 duplexes and on the second day I found this fun looking creature in the first unit and it scared the heck out of me because it was about 4 feet up the wall and I was about 1 foot away from it and it moved and then jumped off the wall like a big cricket. it sort of hops and crawls, one of the local natives on the island said it was "A Cray" and he said they mostly stick to the water and didn't know why this one was so far inland. As you can see it has a pretty big looking stinger and it looks like about 6 legs and 2 large antenna, sorta looks like a deformed grasshopper. If anyone knows what this is I would love to know, since Google images didn't have anything like it and all I can find is crayfish with a search. Brad
This is a female long-horned grasshopper (Orthoptera: Tettigoniidae) in the subfamily Rhaphidophorinae. Commonly called cave crickets or camel crickets (because of their predilection for dark, damp habitats and somewhat hump-backed appearance), they basically are harmless, but can become nuisance pests indoors. The ‘stinger’ actually is its egg-laying organ, called an ovipositor. See http://www.ces.ncsu.edu/depts/ent/notes/Urban/camelcrickets.htm and http://en.wikipedia.org/wiki/Cave_cricket for more information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

I would like to thank Ed Saugstad, retired entomologist; Sinks Grove, WV. for solving my weird bug question, you guys rock. if you could relay this message to him that would be awesome. "thanks Ed."

1547 To explain, I woke up this morning to find these bugs on my body (noticed it while I was in the shower). I found nine of them actually on my body, (four while in the shower and four afterwards), four on my bathroom floor, and one in my bed (I immediately washed my sheets, so not sure if there were more in there). I had to pick them off my body because they were attached (sucking blood or something). As you can see in the first picture I attached that is the back of my left knee, sometimes they left white bumps with red around them, and sometimes they made those dark red marks. (I picked two of of where the dark red marks are, the bumps were there when I awoke.) The next pictures are different pictures of the bugs themselves. They are round, and I can't tell how many legs they have. Some theories I've heard so far today is that they may be newborn ticks, chiggers, or some type of bed bugs. I live in northern Virginia, a bit outside of D.C. and I was in someone's wood-type backyard on Wednesday, September 12th (today being Saturday, September 15th). I have showered since then so am not sure where or how they came about. Some help on this topic would be greatly reassuring. Karin.
Your problem appears to be ticks which could be cause for some concern. They are common in Virginia and many of them carry diseases including Lyme Disease. Symptoms of infection are not always obvious for some period of time. You may be wise to educate yourself on potential health risks and talk to your doctor. These two web sites are a good place to start.

1546 Hello Bugman, My name is Joshua and I work outside of Ft. McKay in North Eastern Alberta. The job site is an oil sands site, with many strange things popping out of the ground at all times of the year. A fellow employee found this bug wandering the halls of our camp which is roughly a few kilometers from site. By his account the bug was trying to fly, but kept bumping into the wall, it never got higher than waist height. The bug has wings. Also it is thought the bug has no antennae. The co-worker trapped the bug in a ziploc container and shortly afterwards (overnight) the bug was dead. Several people onsite have tried identifying this mysterious bug, but none have came up with a solid concrete answer. May I also mention, that onsite we have individuals from all over the world, mind you none of them are entomologists, but like previously stated, no one can identify this creature. Thank You Kindly, Joshua
This is a giant water bug (Hemiptera: Belostomatidae), a.k.a. toe biter or electric light bug. They are voracious predators on aquatic invertebrates as well as the occasional tadpole or small fish, and can deliver quite a painful ‘bite’ if mishandled. See nos. 1513, 1498, 1457, and 1378 for other examples. They are quite good fliers, and often are found far distant from any source of water. See http://www.eduwebs.org/bugs/giant_water_bug.htm for more information. Ed Saugstad, retired entomologist; Sinks Grove, WV.
~~~~~~~~~~~~~~~~~~~~~~~

See picture 1513 for more info -- this is a water beetle, or "toe biter", they are not overly common, but most people get to see one or two in their lifetime. Catherine

1545 Saw this guy walking along the edge of my computer monitor. He was moving quite slowly but when I went to illuminate him with my flashlight he reared up a bit like a praying mantis.
He was only about 3/4 inch long but looked pretty weird. Was that a stinger on his tail as a bright red spot? Those red eyes were pretty cool too. I brought him outside and put him on my bushes since I usually don't like killing any insects. I would have let him stay but I wasn't sure he would sting me or not. Photos were done with a Sony 707 5mp in macro mode. That Carl Zeiss lens is fantastic. That camera about 5 years old. Thanks in advance for your info. I live on Long Island New York north shore area east end. Jay
This is a nymph of an assassin bug (Hemiptera: Reduviidae); possibly in the genus Zelus - see http://www.naturemanmatt.com/zelus.jpg. Assassin bugs are general predators on other small arthropods and thus usually considered beneficial. However, larger specimens are capable of delivering a painful ‘bite’ if mishandled. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1544 Hello, We have been finding this bug and it's tiny offspring in our kitchen cupboards and bathroom recently. We also find something very similar although it has more legs and seems to have one very long single tentacle like hair as well - that is very weird! When we find and kill one of these they immediately turn white! We are worried it may be something serious and there may be a nest somewhere... Can you identify it and let us know how we can get rid of it please. When we find the other similar bug and can get the camera in time we will send a further photo. North Vancouver, B.C. Kind regards, Ken.
This appears to be a firebrat (Thermobia domestica; Thysanura: Lepismatidae) - see http://lancaster.unl.edu/enviro/Images/Insects/firebrat.JPG for an image. They are considered household pests, but seldom do extensive damage. See http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7475.html for a fact sheet that includes control recommendations. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1543 We found this guy in near our moms garden could you help us identify it please. Michell Lathrop

This caterpillar is in the family Saturniidae (giant silk moths). Specifically, it appears to be a larva of the Imperial moth (Eacles imperialis) - see http://pick5.pick.uga.edu/mp/20q?search=Eacles+imperialis for images and much more information on this species. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1542 Hello, I’m from Montreal. Canada, every year at the same period we get the same bugs in the house, they stay for about 2-3 months starting in July. We live in the suburbs and we are located right besides a field of what looks like a wheat field. From what I’ve seen these look like ground beetles but wanted to be certain. Thanks for your help. Best regards. Norbert
These are indeed ground beetles (Coleoptera: Carabidae). They are for the most part general predators on other small arthropods; a few ‘rogues’ are seed feeders. Yours appear to among the ‘good guys.’ Ed Saugstad, retired entomologist; Sinks Grove, WV.

1541 Southern KY . Bug eat bug was next to pine tree on a swing rope . Like to know the one that's doing the eating. Would be hard to tell the one being eaten. So many differentt dragon flies . It might be a young one to ?. THANKS! Joe

The insect doing the eating is a nymph of an assassin bug (Hemiptera: Reduviidae); likely in the genus Pselliopus - see http://www.uky.edu/Ag/CritterFiles/casefile/insects/bugs/assassin/pselliopus1.jpg for an image. Assassin bugs are general predators on other small arthropods, and larger specimens can give a painful ‘bite’ if mishandled. The insect being eaten appears to be a wasp of some kind. The dragonfly appears to be in the family Aeshnidae (darners). Ed Saugstad, retired entomologist; Sinks Grove, WV.

1540 Hello, I found two of these spiders just days apart on my back deck in the cool shade. I have never seen anything like them. They both had the identical markings. I live in the Annapolis Valley, Nova Scotia. These pictures were taken in late September 07. If you could tell me what they are, I would really appreciate it. Thank you. Melissa
This a female orb-weaving spider (family Araneidae); likely in the genus Araneus (see http://www.educared.org.ar/tamtam/kmages/Araneus-diadematus.jpg for an example). They all are harmless to humans, and if you scan down through this site starting with no. 1534, you will find many more examples. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1539 This insect usually appears around late August in an area just south of Algonquin Park Ontario Canada. I recall it was called something like Hagranite or Hygranide but I have not been able to research it, probably because I don't have the correct spelling or perhaps not the correct name at all. It looks like a giant termite with wings. The mandibles are not decoration and I have seen others of the species with much larger mandibles possibly the difference being male or female versions. Jim
This is a female dobsonfly (Megaloptera: Corydalidae). Their larvae (naiads) are aquatic predators called hellgrammites; they sometimes are used for fish bait. Female dobsonflies can deliver a painful bite if handled carelessly. Males have very long and slender mandibles that look fearsome, but are incapable of more than a slight pinch. See http://www.uky.edu/Ag/CritterFiles/casefile/insects/dobsonflies/dobsonflies.htm for images and more information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1538 We found this grub inside our home just north of Barrie, ON. We live in a country setting, a large yard surrounded by a wooded lot (mainly oak, maple and birch). We're not sure how it got in the house, but it could have come in with one of our animals (cats and dog). It is about an inch long, very round, with an incredibly rubber-like body. It looks like a grub but I have been unable to find any information on grubs that aren't white. Thanks for the help! Lindsey
This could be a mature larva of a rodent bot fly (Diptera: Oestridae, subfamily Cuterebrinae). See http://www.radil.missouri.edu/info/para/zebra/display.asp?slide=15 for a larva that was removed from a nodule on the shoulder of a rabbit (see http://www.radil.missouri.edu/info/para/zebra/display.asp?slide=14 ). When the larvae are ready to pupate, they emerge from their host and seek a place to pupate, usually in the soil or ground litter. See http://www.michigan.gov/dnr/0,1607,7-153-10370_12150_12220-26354--,00.html for much more detailed information on these parasites. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1537 I have found a couple of these insects in my house in Prince George, BC, but have never encountered them before moving here. There are a couple of large pincers at the end of the largest appendages. Does anyone know what they are? Sincerely, Amanda
This is a pseudoscorpion, an arachnid in the order Pseudoscorpionida. They are general predators on other small arthropods and are harmless to humans. See http://ohioline.osu.edu/hyg-fact/2000/2062.html for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1536 I found this insect behind my drapes. I live in the Northern part New Jersey in the United States. The insect measures about 1 inch long and 1/4 to 1/3 inch wide. It has a whitish underbelly.

This is a stink bug (Hemiptera: Pentatomidae), and like no. 1514, it resembles the brown marmorated stink bug (Halyomorpha halys), an Asian species recently introduced into North America - see http://www.ento.psu.edu/extension/factsheets/brownMarmoratedstinkbug.htm They will invade houses in search of overwintering shelter, but will do no harm there. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1535 Hi, this big wasp, about 3/4 inch long, was found in Québec (a little town called Saint-Amable). I dont remember seeing this when I was younger (5-8 years ago). Its not the 1st time I see this. My mom found it in the hallway, it was weak, so she killed it. Thank you for reading this and answering my questions.
This is a paper wasp (Hymenoptera: Vespidae); likely in the genus Polistes. Unlike their cousins, yellowjackets, their nest is open in structure (see http://www.coopext.colostate.edu/TRA/PLANTS/images/wasps/Polistes-dominulus-nest.jpg ), and they tend not to be aggressive. However, I can assure you that they do have a painful sting! Ed Saugstad, retired entomologist; Sinks Grove, WV.

1534 I am hoping someone can help identify this spider. I have not seen one like this around here before (Vancouver Island - Nanaimo, BC, Canada). Large abdomen, maybe 1x1.5cm. Distinctive markings on legs and top and bottom of abdomen. Large, very strong web high over the front entrance of the house. Thanks in advance, Adam
This is a female orb-weaving spider (family Araneidae). These impressively sized spiders all are harmless to humans; if you scroll down this site starting with no. 1527, you will find many other examples. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1533 Hello, I live in Boston Massachusetts, last week while I was about to make some spaghetti…I found some larvae inside the box with the spaghetti. Upon further inspection I discovered more of the same larvae in almost all of my boxed pasta (both opened and unopened packages), and other dried food stuffs in the same cabinet. The picture I am sending is of the same larvae found inside a Crystal Light drink mix container. The drink mixes were in individual sealed cups inside of this container. Please help me identify what these pests are so I can pick the right action to get rid of them quickly!! Thanks. Tara

These are larvae and shed larval ‘skins’ of beetles in the family Dermestidae; several species in this family can be household/pantry pests. These specimens appear to be in the genus Anthrenus. Although Anthrenus spp. usually are referred to as furniture or carpet beetles (both the larval and adult stages will damage furs, woolen and silk fabrics); the larvae also will feed on seeds, dry pet food, cereal products, etc. You should inspect all infestable products in your pantries for signs of these insects, discarding anything found obviously infested and thoroughly clean the pantries themselves. Then, keep all infestable products in insect-proof containers or under refrigeration. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1532 I took this picture of an insect we always find on our balcony in Brampton, Ontario. This one is about an inch long. I see these every year, especially on the windows and screens. What is this insect? I am sure it is very common, but I have no idea what it is. Adam.
This is a leaf-footed bug (Hemiptera: Coreidae). Specifically, it appears to be a western conifer seed bug (Leptoglossus occidentalis); see http://www.forestry.ubc.ca/fetch21/FRST308/lab2/leptoglossus_occidentalis/leaf.html. This species can be a nuisance pest when they enter homes in the autumn in search of hibernation sites. If you scroll down through the images on this site, you will see many other examples, including nos. 1253, 1218, 1177, 1152, 1141, 1127, and 1101. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1531 Hello, found this on my car tire a week ago so mid September. It is sitting on a 15inch tire, the picture was taken near Perth, Ontario. I have never seen anything like it before so hopefully someone knows what this is. Troy.
This is a female ichneumon wasp (Hymenoptera: Ichneumonidae) in the genus Megarhyssa - see no. 1437 for another example. They use their long ovipositor (visible at the end of its abdomen) to bore into wood in order to lay its egg in the tunnels of its prey, larvae of wood wasps such as the pigeon tremex. See http://www.cirrusimage.com/hymenoptera_ichneumon_megarhyssa_fem.htm for images and more information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1530 Hi! My daughters came in the house screaming after seeing this. Never seen it before. Does anyone know what it is and if it is dangerous? Thank you so much! I live in Ocean City, MD Colby

This a wheel bug (Arilus cristatus; Hemiptera: Reduviidae); see nos. 1464 and 1455 for other examples. They are general predators on other small arthropods and ths may be considered beneficial. However, they are capable of delivering quite a painful ‘bite’ (more of a stab) if mishandled. See http://www.hiltonpond.org/ThisWeek030901.html for much more information on these formidable creatures. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1529 I found this spider sharing my shower with me 4 days ago. I became curious when I saw the stinger. It was very fast and found in the Pittsburgh area. Could you please identify this for me? Thanks so much. Valene
This appears to be a male spider in the family Agelenidae (funnel web/grass spiders). They often are mistaken for wolf spiders, but they lack the wolf spiders’ greatly enlarged front eyes, and have longer spinnerets. Males often wander quite some distance from their webs in search of mating opportunities. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1528 Hello There, My neighbor found this bug along with a carpet beetle in the crease of her mattress. She thinks it might be a bed bug. Would you please kindly shed some light on this situation. Thank you very much for your assistance. :) Cheers, Vince
Definitely neither a bed bug nor a carpet beetle larva; it could be a very young and badly damaged cockroach nymph. However, the image quality is not sufficient for me to guess any further. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1527 This rather large spider was seen in Fremont, California. With front and rear legs extended, it measures approx 2-2.5 inches. Can you identify it? Thank you, Gloria

This is a female orb-weaving spider (family Araneidae). Females of several North American species can be quite impressive in size, but all are harmless to humans. If you peruse the images on this site, you will see many other such examples. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1526 Hi, I work near Carp (Ottawa), Ontario and for the past few days dozens of these flying insects have been hitting and landing on my office window! They have very red backs ... very visible as they fly away! I wonder if someone can identify them for me? Thanks in advance, RP
This is a box elder bug. For other examples see #1469 & 1499. For more information and control suggestions visit our Box Elder Bugs web page.

1525 We live in Brossard, Quebec. These are 2 different spiders on our property. The first is a black spider with yellow markings that we can only get a good shot of from the underside. The top side does seem to be yellow and white. The body is the size of a kidney bean (or a little smaller).
The second is a spider everyone is calling a jewel spider. It is brown. This picture is of a small one, the size of a quarter, but there are very large ones all over our neighborhood, and their webs are extremely strong compared to what we're used to around here. The largest one we've spotted was the size of a Ritz cracker from end to end. Tanya
These are both orb-weaving spiders (family Araneidae). The spider on the left is in the genus Argiope, likely the garden spider or black and yellow argiope, Argiope aurantia - see http://www.cirrusimage.com/spider_argiope_aurantia.htm for images and more information. The one on the right may be in the genus Neoscona - see http://kenfuller.exactpages.com/hentzs-orb2.JPG for an image. All orb weavers are harmless to humans. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1524 We found this guy/gal running across our living room floor, our guess is wolf spider, we live in Regina, SK.. Jim
This is not a wolf spider, but an orb-weaving spider (family Araneidae) that is in the unusual position of being out of its web (see no. 1495 another suchple). They all are harmless to humans. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1523 Hello, Here in Ancaster, Ontario we recently found this little monster crawling along the floor in our basement. You could hear it on the hardwood floor! Sorry no penny for perspective but it is in a large yogurt container. I live near a large conservation area, which does have a small stream. We have 2 small children in the home and my wife is very concerned. Thanks in advance. Todd

This spider could be in the family Amaurobiidae (hackledmesh weavers) - see http://www.oeko-msc.de/AMAUROBIUS-FEROX.JPG for an image. They are harmless to humans. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1522 Hi, This fellow is about 3/4” long, when pestered curls up in a form of ball, and we found in our toilet every time but one. That time I found it in the shower stall. Does it come from the septic tank we have? Showed up mostly in the summer starting in late spring, more or less and when I put it in a baggie to show people it almost chewed its way out in about 1/5 hours so it can bite. Is it a problem, why only in the toilet, we have three bathrooms but only found this fellow in the one and no where else but the shower once. I have found them near my office as well once in the large garbage can when it was damp and wet in the bottom and it is also fast. We live in the Peace River country, Taylor BC, on the river bottom. Pastor Wally Pohlmann This is a rove beetle (Coleoptera: Staphylinidae). They are general predators on other small arthropods and have very strong jaws for their size. Specimens as large as yours can give a slight nip, but otherwise are harmless. Their occurrence in your house likely is a result of their searching for prey. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1521 Hi. I live in Harrow Ontario. These bugs have popped up in large numbers seemingly all around the house in the past 2 weeks. They fly and as I said seem to be in most all areas.. Kitchen, dining room, bathroom, basement rec room etc. I thought they were fruit flies but do not have red eyes. They are quite small. How do I get rid of them? Thanks, GP
This appears to be a planthopper/leafhopper (order Homoptera) of some sort. (See http://www.biosurvey.ou.edu/okwild/misc/images/fulgorph.jpg for an example). However, the image is too fuzzy for me to see diagnostic characters. These are not ‘normal’ household pests; I have no idea why they would occur in such numbers indoors - you need to determine how they are entering your home, and take corrective actions. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1520 Hi, We live in Kingston, Ontario. We were sitting outside of a pizza shop when we noticed this bug sitting on the glass of the store. We put it into a container and brought it home with us to try and find out what it is. Does anyone know? We thought maybe it was a butterfly or a moth of some sort, but it has no antennae. Maybe they were knocked off? I have become a little attached to it and set him on the tree in our backyard. Can anyone help? Dale and Kim Higgins.
This is a sphinx moth (Lepidoptera: Sphingidae); specifically, it appears to be a pandorus sphinx - Eumorpha pandorus - see http://www.silkmoths.bizland.com/epandoru.htm for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

That’s a Pandora sphinx moth! Pat.

1519 Hi, I have the symptoms of bedbugs. I have bites in the morning when I wake up but strangely only on the backs of my legs and bottom. I can find no bug dirt. I've dismantled by bed and found these bugs dead or partly dead underneath. They don't seem to look like the pictures of bed bugs that I've seen.   I've washed the bedding and bagged it. Vacuumed my room and dusted mattress, box spring bed frame and baseboards with a chemical that says it kills bedbugs and moved to another room. The other room has also been vacuumed an is mostly empty of furniture. I'm sleeping on a mattress from the top bunk of my son's bunk bed. I have two boys who have separated rooms and have not been bitten (yet). Even in this new room I have woken up bitten again. This time one bite on my wrist the rest again on the back of my legs and bottom as before. The bites are red and swollen and sometimes in clusters but don't seem very itchy. The swelling disappears over the day. What do you think? Thanks.   Janet
I'm not sure what these insects are but they don't look like bed bugs.   Perhaps Mr. Saugstad can tell us. The reactions to insect bites can vary widely from one person to another, even in in the same family. Your description leads me to believe you have a flea problem rather than bed bugs. In either case you have taken some of the steps to eliminate them without success. If you have pets, have them treated for fleas by a vet then have a professional inspect the home to identify the source of your problem. Prolonging proper treatment will only result in a population growth.   Larry Cross.
                       ~~~~~~~~~~~~~~~~~~~~~~~~~
These are click beetles (Coleoptera: Elateridae); likely accidental intruders in your home. They would not be responsible for the bite symptoms that you reported. As for the bites, attempting to determine the cause without actually catching something in the act of biting usually is next to impossible. Not only do most bite marks look pretty much alike, but there are several other conditions that can be mistaken for arthropod bites. For some examples, see http://www.ca.uky.edu/agc/pubs/ent/ent58/ent58.pdf Ed Saugstad, retired entomologist; Sinks Grove, WV.

1518 I found this on my porch this morning, and im not quit sure on what it is. I have a 2 year old daughter and small dog, and want to know if this is harmful. Thank you. Steve.

This is a very harmless (unless you’re a plant) larva of a sphinx moth (Lepidoptera: Sphingidae); likely in the genus Hyles. The caterpillars of two species in this genus (Hyles lineata, the white-lined sphinx, and Hyles gallii, the bedstraw hawk moth) are extremely variable in color pattern, but almost always have an orange ‘horn’ at the end of the abdomen. See http://www.silkmoths.bizland.com/hlinelin.htm and http://www.silkmoths.bizland.com/hgallii.htm for some examples. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1517 Hi! I'm from Pittsburgh, PA and this little bug has been appearing in our house frequently lately. We never saw one before, and about June 15 they started turning up. They largest are about 1/2 inch long, though most are smaller than that. They don't move around much unless we bother them. Once we come close to them they jump, and can hop about 6-8 inches. They mostly turn up around the inside of our back door, though lately we've found them in other parts of the house. We don't live near any streams or bodies of water, though we do live just outside of woods. Thanks for any help to identify them and figure out what will get rid of them! Nathan
This likely is a jumping bristletail (Archeognatha: Machilidae) - see http://www.maisonleonprovancher.com/napm/images/insectes/5-Archeognatha/Machilidae.jpg for an image. Your bristletails likely wandered indoors by accident, and should not take up housekeeping there. They generally are found in leaf litter and are not considered pests as are their cousins, firebrats and silverfish (see http://www.discoverlife.org/mp/20o?search=Archeognatha). Ed Saugstad, retired entomologist; Sinks Grove, WV.

1516 Hi, I found this caterpillar in Maple Ridge, British Columbia, in early September. Besides the large brown area in the front it has a V-shaped purple ridge on its posterior. Could it be a type of gypsy-moth? Thanks, Siena Locher-Lo

I am writing this message in response to a Pest Photo ID request on your website...which I love, by the way. This photo appears to be of a Polyphemus Moth (Antheraea polyphemus) caterpillar. They range throughout North America, and all Canadian provinces except Newfoundland. (See http://bugguide.net/node/view/427). The larvae will feed on leaves of broad-leafed trees and shrubs, so there is a possibility of some damage to your garden, however, the adults do not feed at all. It is most certainly not a Gypsy moth larvae, so, in that, you don't need to worry. Nice photo, though!

This appears to be a larva of the polyphemus moth (Antheraea polyphemus; Lepidoptera: Saturniidae) - see http://www.ubcbotanicalgarden.org/potd/2005/08/antheraea_polyp.php . Collectively known as giant silk moths, members of this family are general feeders on the leaves of many trees and shrubs, but seldom are abundant enough to cause any real damage. Ed Saugstad, retired entomologist; Sinks

1515 We live in Chicago, IL in a 100 year old house. These have been found swarming in our basement near our laundry area. They are of various sizes (these are among the biggest) and don’t last long. This is the second year they have appeared. They appear to be ants. Hopefully not carpenter ants. Wondering if anyone can identify them. Thanks. Ashley
These are ants, but definitely not carpenter ants. Check out the University of Illinois Extension bulletin at http://web.extension.uiuc.edu/champaign/homeowners/020323.html for hints on ant control in the home. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1514 Please tell me what this bug is. It is in McLean, Virginia and it is in our home, everywhere! Well, at least a lot of places. And it can fly. Thanks.

This is a stink bug (Hemiptera: Pentatomidae). The image is too fuzzy to be certain, but it does resemble the brown marmorated stink bug (Halyomorpha halys), an Asian species recently introduced into North America - see http://www.ento.psu.edu/extension/factsheets/brownMarmoratedstinkbug.htm They will invade houses in search of overwintering shelter, but will do no harm there. Ed Saugstad, retired entomologist; Sinks Grove, WV.
~~~~~~~~~~~~~~~~~~~~~
I saw picture 1514 and I have them in my apartment too. I live in Fairfax, Virginia (very close to McLean) and we found out that it is a brown stink bug. Katherine

1513 This bug was found in Rosedale, Chilliwack, BC. Angela..

This is a giant water bug (Hemiptera: Belostomatidae), a.k.a. toe biter or electric light bug. They are voracious predators on aquatic invertebrates as well as the occasional tadpole or small fish, and can deliver quite a painful ‘bite’ if mishandled. See nos. 1498, 1457, and 1378 for other examples. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1512 Literally, gallon buckets of these have wormed their out from our cement block garage in the last four weeks -- as the weather has cooled down a bit here in southern Pennsylvania. The foundation of the garage is railroad ties; the ties have been there two years. We had a lot of Japanese beetles this summer, but we have some every summer and never anything like this. Plus, when one squashes these guys, the goo is black, not the yellow/orange of the squashed Japanese beetle. Last week we had a few days in the high 80's and the migration slowed down to a trickle; now we're back in the 70's and wriggles are back in the quarts/per day. Susan
These are larvae ("white grubs") of a beetle in the family Scarabaeidae, which includes Japanese beetles, June beetles, etc. It would be interesting to find out exactly where they are coming from; many species feed on plant roots or dung, but some are found in decaying wood. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1511 Hello; I live in Southern New Brunswick, Canada and the exterior of our house is covered with these insects. They are about a ¼”-3/8” of an inch long and when squashed they have a foul, smell. They only appear on warm Fall days, usually, They squeeze into the seams of the siding and in and around the Corner Boards of the house. They also squeeze between the Doors and the weather stripping, and when the door is opened they drop inside. I have had lawn care people look at them, to identify, no luck. I have had a sample sent to the Agricultural College. They Piggy back on Fire wood brought I for the wood stove. They are not present in the spring or summer only the fall and only on Warm days, disappearing at night. What are They and How do I make them Go away. Thanks Pat ( Excellent Site)
This bug bears a superficial resemblance to Ischnodemus falicus (Hemiptera: Blissidae), a species that feeds on marsh grass; they may be entering your home in search of overwintering quarters. Their relatives, chinch bugs (Blissus spp.), give off a foul odour when crushed, so the smell you noted might well be expected. There likely is nothing you can do to control them; at best you may be able to limit their intrusion by sealing as many cracks and crevices in your home as possible and you might consider consulting a pest management firm about a perimeter barrier treatment. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1510 Hello, I live in the South East of England and these are appearing upstairs in the house (so may be coming in from the roof?) in September. Can anyone help in identifying it? Thanks in advance, Paul.
This is a fly larva; I suspect that it could be that of a soldier fly (Diptera: Stratiomyidae). These larvae usually are found in accumulations of decaying organic matter, including manure, composting vegetation, highly polluted water, etc.. Occasionally, they have been reported indoors when moisture has accumulated around the base of a commode or when a bee's nest has been removed. When mature, they crawl away in search of a drier place in which to pupate. See http://www.flycontrol.novartis.co.uk/species/soldierfly/en/index.shtml for more information on a cosmopolitan species in this genus and http://www.flycontrol.novartis.com/images/figure_33.gif for a drawing of a larva. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1509 Here's two views of my orb weaver. She/he is somewhat different from those I've been looking at on your wonderful website. This one's shell is about the size of a dime. I found him/her on our sandblasted pine front door late in September 2007 south of Tijeras, NM. By the way, I want to tell you how much I appreciate the pest identification information on your wonderful website. Thank you, Merle and Nancy Elson
As you likely already knew, this is an orb-weaving spider (family Araneidae). Specifically, it appears to be Araneus gemmoides, sometimes known as the cat-face spider - see http://www.colostate.edu/Dept/CoopExt/4dmg/images/catFace6.jpg. It is harmless to humans. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1508 hi, fabulous website! please help me identify these bugs that we have found on our bedspread. they have wings, are smaller than a grain of rice, and are brownish-red in color. they are the tiniest bugs short of a flea that i have ever seen with a naked eye. any information you have on these would be much appreciated! Kelly Cord. Guilderland, NY

This beetle appears to be in the family Bostrichidae, that includes a few species of economic importance such as false/horned powder post beetles and lesser grain borers http://www.forestryimages.org/browse/detail.cfm?imgnum=1233134. You might want to examine any exposed unpainted wood in your house for the presence of tiny emergence holes and dust-like frass - see http://www.doyourownpestcontrol.com/ppbeetles1.jpg and http://ohioline.osu.edu/hyg-fact/2000/2090.html. Also, if you store any whole grains such as wheat or maize, you might want to check that for signs of damage as well (see http://www.forestryimages.org/browse/detail.cfm?imgnum=1233134). Ed Saugstad, retired entomologist; Sinks Grove, WV.

Just wanted to say thank you for posting my picture so quickly, and for Ed Saugstad's help in identifying this bug. we were told when we moved in to our house almost 6 years ago that there were powderpost beetles in it...we had it treated by a professional exterminator at that time, and we're hoping these flew in through the window fan from outside. that's what my husband thinks happened, as we have not seen any holes or wood powder anywhere. thanks again! Kelly, Guilderland, ny

1507 Hi. I live in Toronto, Ontario; this wasp-type-thing flew into my apartment today (early fall). It has long antenna that are black, yellow and constantly moving. It's body is all black except for a white spot on its back. It's legs are black and yellow. It looks like the mud dauber, except it's abdomen is longer and attached more closely to the thorax. It's mouth/pincers seem quite small compared to other wasps I've seen. Any idea what it's name is? (he won't answer to Frank...I've already tried) :) thanks, Cheryl
Although this does bear a superficial resemblance to the yellow and black mud dauber, it more likely is a parasitic wasp in the family Ichneumonidae - see http://www.myrmecos.net/insects/Ich1.JPG for an image of a similar specimen. Ichneumonids are all parasitic on other insects or spiders. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1506 Hi! Live in Grand Falls NB and wanted to know what kind of Bug is it. It's in my flower garden and eating the leaves. I could I get rid of it. Thanks.

This appears to be a lily leaf beetle (Lilioceris lilii; Coleoptera: Chrysomelidae). It is native to Europe, but was introduced to North America in the 1940s. See http://www.uri.edu/ce/factsheets/sheets/lilyleafbeetle.html for more information, including control recommendations. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1505 I live outside of Halifax, NS and have found this spider on my deck for the past two days. I was hoping someone could help me to identify it. I was wondering if it's a wolf spider...Steve Prosser
This is an orb-weaving spider (family Araneidae) that somehow has wandered away from its web. See nos.1494 and 1495 for other examples. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1504 This caterpillar was crawling along the blind on our deck. This was September on Salt Spring Island in British Columbia Canada. I sent him on his way, thinking he might be a good guy.... or was I wrong and should have squished him? B. Brazier
This appears to be the larva of a dagger moth (Acronicta spp.; Lepidoptera: Noctuidae); see http://zipcodezoo.com/Animals/A/Acronicta_impleta.asp for an example. These caterpillars can be highly variable in color pattern. They feed on the leaves of a wide variety of trees and shrubs, but seldom appear to cause any substantial damage. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1503 This appeared recently on my windowsill, although I usually keep them very clean. It seems to be attached to the metal window frame. Can you tell me what it is, and what I should do to remove it? Near Baltimore Maryland. Barbara

I suspect that this object may not be of insect origin, but possibly could be fungal or myxomycete (slime mold) in nature - see http://www.capsandstems.com/graphics/Fuligo_septica-1.jpg for an image of a fruiting body of a slime mold. In any case, scraping it off and washing the area with a disinfectant should help. You also might try contacting your county office of the University of Maryland’s Cooperative Extension Service to see if they can be of assistance; see http://extension.umd.edu/local/index.cfm for contact information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

1502 We found this larva on the floor of our Idaho school in late September. It has no obvious legs and moves forward in an alternate rocking motion. Anyone know what it is? Mary Ann.

We figured it out...soldier fly larva......Thanks! Mary Ann

1501 I have checked many identification pages to no avail. This was crawling on our ceiling in St. Catharines, Ontario house on September 22. I believe it bit my daughter's arm. She's OK but it swelled quite a bit and she said it hurt and was itchy. Lynette.

This is a jumping spider (family Salticidae); they are active hunters, having excellent eyesight for spiders
(see http://tolweb.org/accessory/Jumping_Spider_Vision?acc_id=1946 for details). Larger specimens are capable of a painful bite if mishandled, but none are considered dangerous to humans. However, just as with bee stings, some individuals may be more sensitive to the venom than others. Ed Saugstad, retired entomologist; Sinks Grove, WV.
