Thank you....

Hello,
I'm one of those people in Ontario that are very curious. I had found a 5cm spider and was curious to know what it was. Well I stumbled upon your website and found all the information I needed with a WONDERFUL picture. So for that I thank you and keep up the good work :)

3100 My name is Carolyn. I live on the South Coast of Newfoundland. This bug is in very high numbers mostly found in our garage and we only see them at night. It is November month and every evening our garage floor is crawling with them. Could you please help us identify it. Thank you
These most likely are millipedes (class Diplopoda). They basically are harmless detrivores/scavengers on decomposing organic material, but can become nuisance pests when they occur indoors. They require moisture/high humidity in order to persist in an environment. So moisture management through lowering indoor humidity levels and elimination unnecessary water sources should discourage them. See http://tinyurl.com/yjvoz4y for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3099 Hello Webmanager, Ordinarily I wouldn't have bothered with such a tiny creature (barely a quarter inch) but I was at a picnic table with camera in hand and it was being just so cooperative, I had to take the shot. The location was central Florida. Thank you Dr. Saugstad for your efforts. Best regards, Jack.
This is a larva of a green lacewing Neuroptera: Chrysopidae). They are general predators on other soft-bodied arthropods (see http://tinyurl.com/3ytuysp for an example), and thus usually considered beneficial. Thank you for the kind words, but I am a Mr. and not a Dr. - I was drafted out of grad school before I could get that far...Ed Saugstad, retired entomologist; Sinks Grove, WV.

3098 Hello, My name is Chris. I live in Connecticut. We have been finding these insects in our basement and feel as though we are being bitten in the house and wonder if this is the culprit. We catch them under a lamp in a bowl of water. I put these under a microscope at at 60x for the photo. Can you please identify them. I have seen pictures of Colembolla or springtails online. Maybe that's what this is? Thanks
for your help.
This does indeed appear to be a springtail (Collembola). These are primitive arthropods that most systemists now consider to be a part of a lineage separate from true insects - see http://tinyurl.com/yh9wgyw for excruciatingly detailed information. Because of the structure of their mouthparts, they would be incapable of biting humans. Unfortunately, there is a lot of misinformation about these creatures on the internet, and a lot of shysters trying to make a quick buck from folks convinced that they can be ‘infested’ with them. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3097 I found many of these bugs (20-30) and casings on my mattress & box spring, mainly at the fold where the pillow top meets the main part of the mattress. I'm in Indianapolis, Indiana. Can you please tell me if these are bed bugs? -Jeff
These appear to be larvae (and/or shed larval ‘skins’; the image is unclear) of beetles in the family Dermestidae (hide/skin/carpet beetles and allies). They will feed on an extremely wide range of organic materials; primarily those of animal origin. See http://tinyurl.com/2efwz8w for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3096 Greetings Webmanager of Pest Control Canada, I reside in Albany, New York. In 10th, Nov, 2010, when I was about to have a shower, I found this little thing in the bathtub. A noticeable feature is that it could leap over quite a distance, I would say it is about a metre. Would this be a kind of crickets? It sounds odd to me because I have not seen one having such a short body as the photo tells. Will wait for your help, thanks a lot. Best wishes, Andrew
This image will not enlarge either and is quite indistinct on the web page, but from your description most likely is a cave/camel cricket (Orthoptera: Rhaphidophoridae). They are wingless, but can indeed leap very well. They tend to inhabit dark, damp environments, and can be nuisance pests when they occur indoors. See http://tinyurl.com/5ncego for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3095 Include any other information that may help identify your photo. (Size, month, season, weather conditions, indoors, outdoors, etc.) This bug is just over 1.5cm long (not counting antennae) and was found dead in my kitchen cupboards. I have seen a couple of them alive at night and they are bigger in size. These are extremely fast and do not light the light. Please tell me it is not a roach or I will be moving to my inlaws while the hubby fumigates. Christa (Kitchener, Ontario)
This is a German cockroach (Blattella germanica), an extremely common and widespread pest species. See http://tinyurl.com/2d97of7 for some control recommendations; fumigation is not a good idea, it may simply create more problems. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3094 All of a sudden I have found 25 of these little moths inside my apartment over the course of 3-4 days, and I don't believe I had any of these in my place before that. I'm not finding them in the closet, but everywhere else in the apartment (a couple in the bathroom, a few on the carpet, a few in the kitchen, and most of them seem to hang out on the walls). I have a window in the kitchen that is almost permanently open but it is screened. Are they coming in from the outside or are they hatching from inside the apartment? They don't seem to be attracted to the light. They don't fly too well either. Victoria, BC, Indoors, October. approx. 1cm long. Do I need to check my closet for sweaters with holes? Thanks.
This most definitely is not a clothes moth nor any other species that would be an indoor pest. Like no. 3092, it most likely gained entry accidentally, and could not find its way out. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3093 Hi; I found this outside my front door. He was about 1.5” in size. I live in the Vaudreuil/St-Lazare area (15 – 20 minutes west off the island of Montreal) and have never seen such a strange spider as this one before. What was strange is that it was so cold (around the freezing point) and he was still moving around. Thought insects go to sleep in cold weather because they are cold-blooded… Let me know what you think. Bernadette Marti

This spider appears to be a hacklemesh weaver (family Amourobiidae - see http://tinyurl.com/29394bn for an image of Amourobius borealis, an Ontario native. These spiders are harless to humans. Many arthropods can remain active (albeit sluggishly) in quite cool weather; their main concern being to find shelter that protects them from sub-freezing temperatures. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3092 Hi - my daughter found this little moth crawling on her dresser this morning. Please let me know what it is. Thanks, M. de Almeida

This moth appears to be in the family Tortricidae; it is an accidental intruder that will cause no harm indoors. However, the caterpillars of some species (such as the codling moth) can be damaging orchard pests. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3091 Hello there, I found this beast resting on its rather impressive web on an unseasonable warm and breezy Sunday afternoon in October in London Ontario. Quite large in general, its body was only slightly smaller than a bottle cap, with its leg span easily exceeding the bottle cap perimeter. I am curious to know if it will attempt to hibernate in the much warmer home this winter and if so I would rather move it now than meet it in a dark hallway late one winters eve. Any insight on this arachnid would be hugely appreciated. The pic is a little dark, I would describe it as brown with its lighter areas being tan/beige, almost yellow even in some areas. Thanking you in advance. Rafe
This is an orb weaving spider (family Araneidae) in th genus Araneus; likely Araneus diadematus - see http://tinyurl.com/23z7492 for an example. This is a widespread species on both sides of the Atlantic Ocean that goes by many common names, including European garden spider, diadem spider, cross spider, or cross orbweaver. It will not survive the winter; females lay eggs in the autumn and enclose them in a tough sac that will protect them until they hatch the following spring. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3090 Hi - first off, your site is FANTASTIC -thank you! We live in Whitby, Ontario, Canada and have these little critters hanging around our kitchen counters - they seem to like to congregate around the toaster but never in the toaster but they have also been found exploring in our kitchen sink when it is dry. We have never found them anywhere else in our apartment or actually in food. We ensure the kitchen counter is clean but they still insist on visiting daily, usually in groups of approx 5 at a time, spread out on open areas of the counter. They tend to sit in one place and only move (quickly) when prodded. Their visits increase in the warm weather but they have been known to appear in the winter as well. Measurement would be approx 1mm wide and 3mm in length. Please help us identify our unwanted guests and how we can finally end their stay! Thank you, Denyse & Matt

The image is not clear enough for a definitive i.d. - can you submit another one? The general shape is consistent with it being a small ground beetle, but those have filiform antennae and these antennae appear to be slightly clubbed. Also, although the size is about right for a flour beetle (Tribolium sp.), the antennae are too long. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3089 My name is Eleanor... This is the same type of spider I found in Cayo Coco, Cuba in November. Picture was not taken by me, but is the exact type I killed over and over again in my room at the resort... Would like to know what it is... please. These were also outside... they managed to get into my room through the gap under the door. Thank you, Eleanor
Although there is some resemblance to a male funnel web spider (family Agelenidae) in the genus Tegenaria (see http://tinyurl.com/2fx74kt for an example), I am not at all confident, and would like to give this one some more thought. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3088 found in an apartment. some dead some alive. Rick. St Catharines, Ont.

This is one of the grain beetles (Coleoptera: Silvanidae) in the genus Oryzaephilus; from the shape of the head, it appears to be the saw-toothed grain beetle, Oryzaephilus surinamensis. However, the merchant grain beetle, Oryzaephilus mercator, is very similar in appearance, the main difference being that the merchant grain beetle can fly and the saw-toothed cannot. Both can be annoying pantry pests; see http://tinyurl.com/2eaf8hb for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3087 Daisy, my golden retriever discovered this 6-legged, 1-cm-long bug crawling on the bedroom carpet in our Southern California home during an unusually hot November 2010. She sometimes eats bugs. Can you identify and tell me whether harmful if swallowed (or in any other way)? Thank you. Millie
This is a ground beetle (Coleoptera: Carabidae), likely in the tribe Harpalini - see http://tinyurl.com/28h2fcl for some examples. This is a very large family, the vast majority of which are general predators on other small arthropods. They would not be harmful if ingested. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3086 Hi! Amazing, wonderful super site! I live in SE Michigan. We recently moved into a new house. I keep seeing these droppings on the kitchen counter, and they always seem to be underneath where cabinets, microwave, etc. are mounted. They are rock hard. I can't seem to find anything, and our two cats don't indicate that they can tell of critters around there either. It is pretty gross and I would love to find out what these are so I can get rid of it! I used a super-macro lens to get the picture, so hopefully someone can help! Thank you sooo much! ~Jen Stephens
This does look more like a rodent fecal pellet to me than anything insect related. Have you tried placing glue boards about? Ed Saugstad, retired entomologist; Sinks Grove, WV.

3085 I live in Madison, WI. This photo was taken in the conservatory at the local public gardens. This indoor facility features rain forest climate and plants. These bugs are about 1/8 inch long. I was fascinated by the large reddish orange "eyes." M.C. Hannon
These are vinegar/pomace flies (Diptera: Drosophilidae). Often (and erroneously) called ‘fruit flies,’ they have been used in genetic research for a great many years. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3084 My name is Tanja, and I live in Vernon B.C. Canada. I found this bug in my kitchen, and in my baby's crib. I'm hoping you could tell me what type of bug this is. Thank you

.This is a case-bearing caterpillar in the family Tineidae, that includes clothes moths and allies. However, there are some species that appear to prefer feeding on old spider webs and the like, rather than clothing. Nevertheless, you might want to check any woolen or silken fabric(s) for signs of chewing damage. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3083 This is actually the bottom of a little beast I found on our bedroom wall in Saskatoon. It's segmented, has six short legs, what appear to be nasty pinchers at the mouth end, and a really weird shape, tapered at both ends. It's also kind of green, so I'm hoping that means it just eats plants. Ideas? Phil.
This appears to be a larva of a green lacewing Neuroptera: Chrysopidae). They are general predators on other soft-bodied arthropods (see http://tinyurl.com/3ytuysp for an example), and thus usually considered beneficial. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3082 Hallo. I am from Syria. what is this insect. Or.lepidoptera pistachio insect?
This moth appears to be in the superfamily Yponomeutoidea, but beyond that, I cannot say. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3081 Greetings, There were two moths like this on the wall next to my front door and they didn't move for about a week. They were identical in size and coloration. Only the one in the photo laid eggs, which have since hatched, and the tiny caterpillars have what appear to be spikes on their backs. They are VERY small. I've searched hundreds of moth images but can't find one like this moth. Hope you can help!
Location: Los Angeles, California, Size: ~ 1 inch, Month: late October. Thanks, John
This is Arachnis picta (Lepidoptera: Erebidae; subfamily Arctiinae)’ known as the painted arachnis or painted tiger moth - see http://tinyurl.com/2e3eyf4 for an image and http://tinyurl.com/2ccm5kc for newly hatched larvae. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3080 I found this little guy in my basement laundry room and I’ve also seen some in my outdoor garage during the summer months. He seems pretty slow moving and appears to be covered in some kind of debris. He’s about 1cm long. I live in Toronto and I’m just wondering what kind of bug this is. Thanks, Ian Carbonneau

This is a nymph of an assassin bug (Hemiptera/Heteroptera: Reduviidae) called the masked hunter (Reduvius personatus). They are general predators on other small arthropods, and can deliver a very painful ‘bite’ if mishandled. See http://tinyurl.com/egdfr for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3079 Hello. I'm hoping you can help. Here's what I know: noticed a brown smudge (like a light layer of Nutella on the door molding one day.) Three days later it turned into this. I live in Los Angeles, CA. . They were on the door molding in the hallway from the garage. Not anywhere near moisture or a source of water or food. The weird thing is that its in a high traffic area too. I'd figure these things would appear in places where people aren't. The were crawling up the wall very slowly and in hours had spread into the house... roughly three to four feet from the cluster. Please know if they are harmful to humans or if they will turn in to Godzilla. Thanks in advance. -Mark

These are very young caterpillars, but I cannot provide a specific identity. There is some resemblance to newly hatched caterpillars of a moth in the family Lymantriidae (tussock moths) - see http://tinyurl.com/d4f6fs for an image - but at this early stage, quite a few different species can have a quite similar appearance. This likely represents an incidental oviposition by a moth that did not find a more suitable location before she had to lay her eggs. They pose no threat ; I suggest simply vacuuming them up and disposing of them. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3078 Found these in my boxspring, but none in mattress and did not get bitten. Are they bed bugs or worms. Thank you so much. Gavin
This is not a bed bug; it appears to be a larva of a beetle in the family Dermestidae (hide/skin/carpet beetles and allies), likely in the genus Anthrenus, that has been denuded of most of its body hairs (setae). See http://tinyurl.com/ox6k2d for an image of one with most of its hairs intact. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3077 I live in Israel. I found this spider in my bathroom last night, and i think it might be a female trapdoor spider. Am i correct? thanks, Omer

This spider appears to be in the family Theraphosidae (tarantulas and allies). It may be Chaetopelma olivaceum, a species known as the Israeli tarantula - see http://tinyurl.com/2ctpb8u for an image. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3076 Hello, we found this spider in our driveway Oct 28/10. It was was a cool overcast day. The body was about the size of a nickel, and very thick prob close to 3/4 in. If u include the legs it was about the size of a toonie (2$ coin) It had 8 legs, and two smaller looking ones down close to face that seemed to aid in its walking, not real sure guess could be just feelers? Its body was orange and the legs where orange but transparent. We moved it to the grassey wooded area so it would not be harmed. Any info on this would be appreciated. Thanks Laura, Sharbot Lake Ontario, Canada. North Of Kingston
This is a harmless orb weaving spider (family Araneidae) in the genus Araneus. It could be a shamrock spider (Araneus trifolium) - see http://tinyurl.com/287wtrc for an example, but some specimens of the highly variable species Araneus marmoreus (marbled orb weaver) can be quite similar in appearance - see http://tinyurl.com/23au5v4 for an example. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3075 Dear Sir, Please identify this pest found in bathroom very frequently. Thanks & regards. pankaj
These are terrestrial crustaceans in the order Isopoda known as sowbugs. For the most part, they are harmless scavengers on decomposing organic matter, but occasionally may damage very tender plants and also may be nuisance pests when they occur indoors. They require abundant moisture/high humidity in order to thrive, so moisture management is key to controlling them. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3074 From: Howard. Seen in New York City apartment. I find these crawling on floor and occasionally up walls. I see them more when it starts getting cold. They are tiny, maybe 2mm in length. Thanks..
This beetle is in the family Anobiidae; likely a drugstore beetle (Stegobium paniceum), although the cigarette beetle (Lasioderma serricorne) can be very similar in appearance. Both species can be pantry pests, feeding on a very wide range of organic materials. See http://tinyurl.com/dba9uj for more detailed information, including control recommendations. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3073 I would greatly appreciate your help in identifying this bug. My 5 year old son found him (dead) at the end of our driveway. We live in Toronto, Canada. The bug was found in mid-October. It's roughly 3 inches in length. Neither myself nor my neighbors can recall seeing anything like this in the area. In the meantime, my son has named it Eye-pod and is displaying it in his room. Regards, Eddy

This is a giant water bug (Hemiptera/Heteroptera: Belostomatidae). Also known as electric light bugs or toe biters, they are voracious predators on other aquatic life, mostly other insects, but also sometimes tadpoles and small minnows as well. They are strong fliers that may be found quite some distance from any water source. See no. 2849 for another example. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3072 Found this guy on a leaf bag while we were doing some fall cleanup. He was about 2 inches across. He was quite happy staying put and stayed on the bag for several hours. As best as I can tell it is a fishing spider. We live in the Ottawa, On. Area. Thanks, Mark

This is indeed a fishing/dock spider (family Pisauridae), in the genus Dolomedes. It most likely is Dolomedes tenebrosus, sometimes called the dark fishing spider - see http://tinyurl.com/2g5kmbp for an image. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3071 Hi there, I have been finding these small brown bugs in my daughters bedroom. Mostly on top of her pillows, one or two at a time. Then none for a few days and then again one or two on her pillow. I found some more on her carpet. Have washed everything in hopes they would disappear, but it doesn't seem to work. Any help would be great. We live in Toronto, Ontario. Thanks! Annette
These appear to be flour beetles (Tribolium sp.; either castaneum or confusum; Coleoptera: Tenebrionidae). Either can be pantry pests; see http://tinyurl.com/29qvhmq for detailed information, including control recommendations. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3070 Hello I live in Thunder Bay, Ontario Canada and I am finding this bug in my bedroom on the wall were the two walls meet and ceiling. they are very small have a white body and black head and they drag this little fibre home with them. Would you be able to tell me what they are, were they come from, why am i getting them, what to do, and are they harmful and ok to have.
This could be a larva of a case-bearing clothes moth (Tinea pellionella; Lepidoptera: Tineidae); see http://tinyurl.com/24o525r for detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3069 Anything you can tell me will be greatly appreciated. These were in my pantry. They seem to be mostly on, in and around a sealed container of Corn Starch. However, while cleaning out everything I have found the cocoon looking ones in folds of the plastic storage bins...even in the crevice of soft drink bottles. Its been a mess cleaning up and trying to make sure I don't miss any of them. I am in south Mississippi along the coast. Thank you. Annette
This could be a cocoon of an Indian meal moth (Plodia interpunctella; Lepidoptera: Pyralidae) - see http://tinyurl.com/28nuugo for an image. These moths are cosmopolitan pests of dry stored food products that frequently infest pantry items; see http://tinyurl.com/2pz6nk for control recommendations. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3068 Hi there my name is Cristina from Brampton, Ontario - I was hoping you could help me identify this tiny crawling size bug. I found two crawling in front of my couch today October 26th and one in exactly the same spot yesterday. It is very very small - maybe 5 mm and black in colour. The winter is fast approaching and we found this is the basement rec room. I have never ever seen this bug before in our home and worry because I have three small babies crawling around all day in that room and wonder if this bug bites? Thanks!
This is a weevil (Coleoptera: Curculionidae) appearing to be in the genus Sitophilus. There are at least three species in this genus that are cosmopolitan in distribution and pests of stored whole grains (wheat, rice, maize, etc.). See http://tinyurl.com/29mttkm for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3067 Hi, Need help to identify this bug. It is only 2.58mm in length and they keep biting my kids in the hair in my backyard. My location is Niagara-on-the-lake, Ontario, Canada. Hope you can help. Thanks. Randy
The image is not clear enough to be certain, but the most likely suspect is a biting fly in the family Simuliidae - see http://tinyurl.com/24nr8od for an example. Commonly known as black flies, blackflies, or buffalo gnats, their larvae develop in oxygen-rich water, usually fast-moving streams. Control can be quite difficult, but DEET-based insect repellents appear effective for personal protection. See http://tinyurl.com/moqcw2 for detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3066 2010, Summer on the deck on a calm sunny warm day late in the afternoon, Hamilton, Ontario.
This is a carrion beetle (Coleoptera: Silphidae) in the genus Nicrophorus ; possibly Nicrophorus tormentosus - see http://tinyurl.com/3a88mtl for an image. The small critters on it are mites, hitchhiking to a new food source. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3065 These are the Spiders I am seeing in my home this fall. October with cold nights and warm days now in Southern WV. Normally I see a few Wolf Spiders but these are new visitors. Are there any risk to our health here or should I find them a new home. Thank You For Your Help, Sid Fleming
I wish that I knew the identity of this species, as I have seen at least one similar to it at our home in SE West Virginia. About all that I can say is that it could be in the family Theridiidae, and that it is not a species of any medical concern to humans. If I can find anything more specific, I will return to this post. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3064 Hello, I am trying to identify this bug which is crawling all over the wall of my house. Thank you in advance for your help! Manon

This appears to be an eastern boxelder bug, Boisea trivittata (Hemiptera/Heteroptera: Rhopalidae). They basically are nuisance pests that seldom do any real harm. See http://tinyurl.com/5haez8 for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3063 Hi. My name is Barb and we saw this strange bug crossing a paved path in front of us in a park near my home on Oct. 12, 2010. It was about 2.5 cm. long and about 2 cm. wide and a purple/navy/green colour. Upon blowing up the picture I could see a greenish deposit behind it. I assume it was a waste product. Thanks for your help.
This is a blister beetle (Coleoptera: Meloidae) in the genus Meloe. Beetles in this genus sometimes are called ‘oil beetles’ because of the oily droplets of hemolymph (‘blood’) they release from their joints when disturbed. This fluid contains a substance called cantharidin that can cause blistering of tender skin and painful swelling. See http://tinyurl.com/y2u2sck for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3062 I am very interested in knowing which insect created this? I found this hanging under the brick under a first floor window; The yellow dotted line is a very nice gold colour, and it does not go completely around the bag. Location ; Barrie, Ontario.

3061 Hi, I found these bugs in my bedroom and I have seen them in my hall closet on the floor. I live in Westchester, NY. I believe i had the same bug about a year and a half ago in my pantry. I was wondering what it is so i can get rid of them. They are under my bed and dresser. And they even were on my beds box spring. They are approximately 1/2 cm long. Thanks so much, Corinne.
This is a larva of a beetle in the family Dermestidae (hide/skin/carpet beetles and allies); likely in the genus Anthrenus. This genus includes several species that can feed on wool and silk fabrics as well as on fur, feathers, taxidermy mounts, accumulations of dead insects, and dried stored food products.

3060 This insect was on the window (outside) today, October 22nd, 2010. We live in Ladner, British Columbia. It's about 1 inch long and the picture says the rest. Can you tell me what it is?
This appears to be another western conifer seed bug, Leptoglossus occidentalis (Hemiptera/Heteroptera: Coreidae) - see no. 3059. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3059 I live in Pickering, Ontario. I found this bug on my upstairs bedroom floor yesterday (October 16) and am afraid it might be a cockroach. My place is clean but I live in a row of townhouses and attached units may or may not be. It was just sitting there on the floor, did not move. It is about 1 inch long. I threw a magazine over it and stepped on it...so it is slightly squashed but I am hoping you can still identify it so I will know if I need an exterminator. I have not seen any others in any part of the house...yet. Thank you.

3058 These bugs were found in Guelph, ON in an apartment. They don't seem to be present in large numbers but they seem to be always around. We began seeing them in the middle of the summer and even with the on-set of cold weather they still persist. They tend to be in the living room where there is carpet and couches and in the kitchen but they don't seem to be in the bedroom where there is a hardwood floor. They are about 2mm long and fly. Thank you for any insight you can provide.
These beetles are in the family Anobiidae; likely cigarette beetles (Lasioderma serricorne).

3048 The bottom of our front door of our home in Cross Lanes, WV was showing signs of rot. So a couple days ago we tried to determine if there were any signs of termites or carpenter ants that might have contributed to it (the house is also 15 years old and this is an area that gets little sun and tends to stay moist). On close inspection we found the rotted wood contained these insects. Can you tell me what they are, and if we should get an exterminator? Do you think the insects caused the rot, or did they just take advantage of the wet wood to live? Thanks for any advice you can offer! Regards - Kathy
At least two of these appear to be ants (the one on the right may be something different), but definitely not carpenter ants; Some ants in the genus Lasius readily chew into moist, rotten wood to make their nests. They do not cause the rot, but make use of it. Ed Saugstad, retired entomologist; Sinks Grove, WV.

3044 Hi. We live in New Westminster, BC, Canada. When we arrived home from holidays yesterday (Sunday), these bugs were all over the outside of the screen door and the painted concrete ceiling beam of our apartment balcony. Some of the bugs are dead. They do not seem to be on any of the plants in the pots on our balcony. We live on the second floor. The suite below has a patio and garden. Their garden had been all cleaned up and weeded while we were away - had been all over grown. The weather here had been warm to hot and dry (no rain for about 35 days) and then it rained on Friday night and Saturday with showers on Sunday. Still cloudy with showers today. There seem to be less bugs today. I thought they might be lacewings, except for the two "tail-like" bits at the back...Thanks for your help Mrs. McSavaney

3036 Hi, In July of 2010 I was vacationing in Arizona south of Phoenix. One morning while out walking in the desert I happened across this little guy. There seemed to be eight legs so I presumed it was a spider although I have not been able to find a photo or description to verify what exactly it is. The bright colouration was the first thing that attracted my eye, and I figured that anything that small (size of my baby finger nail) and that flashy probably had a fairly potent self defence mechanism. The other interesting feature was the hairiness of the body. Any suggestions... David

3021 Hi- I am in Stuart, FL. Seen alive- this insect was longer, thinner and sinuous- resembling a small centipede scurrying (about 1 inch per second) across my carpet- headed for my bed where for two months I have been bitten in my sleep about every five days. Specimen was mauled when I mangled it - mashing it in a paper towel. Could this be the persistent culprit? Thanks Ed
I must admit that this one has me puzzled; about all I can say is that it appears to be a beetle larva, and as such would be extremely unlikely to be responsible for any bites.

3010 This beetle flew in to rest on the back window of a car behind St. Croix, Nova Scotia. It was a very hot, humid day near a river, lake and forest. It's body is approximately 1.25 inches long. People have seen them but no one seems to know what they are. Thanks!
This is a long-horned wood boring beetle (Coleoptera: Cerambycidae) in the genus Monochamus.

3008 Found this one in my house on Monday evening June 12th, Victoria, BC. About 1.5 inches long, 6 legs. Flew very slowly & with a loud noise. Weather was okay for July, warm (~ 20 C) but not the usual hot, no rain for a couple of weeks. Have seen several since, as we walked near tall grass along the Dallas Rd cliffs. They sit still when you are walking & really make a hissing noise when you step close by them. What is it? Ian

The most likely to be encountered is Tegenaria domestica - see http://tinyurl.com/5owuzh for detailed information. Ed Saugstad. Retired entomologist; Sinks Grove, WV

3006 Hi - I am wondering if this is a beneficial wasp, or garden pest. I thought at first, that it might be a vine borer - but don't think so now. I live in west lower Michigan, and this was just taken a week ago (mid July). I am finding vine borers in my zucchini, but I question whether this is the culprit. Thanks! Debra

3000 My name is Mark Live in Grafton, Ontario. North shore of Lake Ontario. This insect showed up the other night. Thought it was a dragonfly at first. Large mandibles and the tail curves around trying to sting when bothered. Any ideas? Thanks
This is a female eastern dobsonfly (Corydalus cornutus; Megaloptera: Corydalidae). They lack a stinger, so the abdominal posturing is harmless. However, its jaws are very powerful, and can draw blood if it bites. The males have much longer but far weaker jaws and can only pinch. Their larvae are aquatic and commonly known as hellgrammites; they also have powerful jaws. See http://tinyurl.com/256o98e for detailed information. Ed Saugstad.

2999 Hi, we have these large (1- 1.5inch) flying insects coming into our backyard and digging there way into the crevices of our patio, literally removing the gravel pieces with its mouth and making a home. We live in Vaughan Ontario, these insects look like huge black ants with wings, they eat grasshoppers which they bring into the holes they've dug up. They just came around in the past few weeks, we have never seen them before, there are about 5-6 flying around in our back yard each with its own hole. I hope you can help us out, they are ruining any opportunity to sit outside and enjoy the weather. Nikki
This wasp is in the family Sphecidae (thread-waisted wasps). It could be Prionyx atratus, a species that specializes in attacking grasshoppers - see http://tinyurl.com/2ulmp9y for an image. These wasps provision their burrows with paralyzed grasshoppers that serve as a living food bank for the wasp larvae. They are not aggressive; about the only way to get stung by one would be to deliberately pick up one of them. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2998 To whom it may Concern; This beetle/bug was caught by my son DJ in the Quadcities of Davenport, Iowa. This bug measures about 4.5 cm in length. It was caught in July while he was digging under our outside patio deck stairs which contains mulch and soil. It is warm and humid during the month of July in Iowa. We have not located another one. It has large red eyes with claws on the front that resemble a crab claw. My son DJ nick-named it the "crab beetle" because of this. Please let us know the name of this little creepy critter.

2997 We've been finding these guys inside the house fairly regularly in the last month or so. I think they're probably soldier beetles but I'd like a more expert opinion. Any ideas what is causing them to repeatedly come inside? He's about 1cm from head to the end of his abdomen. They wander about, moving relatively slowly when inside and don't seem very inclined to fly, and seem to occur in the back of the house which opens to the garden. thanks! and kudos on your very useful site.

2994 Attached is photo of nest and busy inhabitants. A full screen blow-up shows fine yellow or cream coloured stripes on abdomen. Nest is currently about the size of a two pound soft margarine container. This is in the Cowichan Valley on Vancouver Island. I have reviewed wasp and hornet identification sites and am not confident in ID, and with this nest in close proximity to firewood and tool storage area, I am concerned over degree of aggressiveness. Would like to leave them if possible, since some info says they are likely to beneficial insect eaters. Bruce W
These are social wasps in the family Vespidae of a type known commonly as yellow jackets, possibly the aerial yellow jacket (Dolichovespula arenaria). These wasps are not as aggressive in nest defence as most other aerial nets makers (such as the bald-faced hornet), and basically are beneficial predators on caterpillars and the like. Unfortunately, the wasp images themselves are not clear enough to differentiate them from the common yellow jacket (Vespula vulgaris), a more aggressive species that occasionally construct aerial nests. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2993 Here is picture of what I think to be the culprit of bites on me. It started out in one location with a quarter size bite. The bite grew to bigger than a CD in about two weeks. Once it got into my main blood stream other circles have appeared all over my body. I have no idea what kind of spider it is but I found it dangling from the inside of a toy box I was building for a customer in my wood shop. The bite is itchy and it's making my muscle tender to the touch as with the other red spots. My location is central Pennsylvania, US. I found two of these spiders so far, one became victim of a shop vac and the other got away. Stephen
This is a cobweb/comb-footed spider (family Theridiidae); it is not a species dangerous to humans, and I doubt very much if it would be responsible for your bite symptoms. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2991 Hello Karen, I assume this to be some sort of caterpillar however I've never seen it move. The white "pods" are particularly puzzling. If it was ever mobile it may simply have "passed on" as they say. It was found in a plastic cabinet drawer kept in our garage here in central Alabama. Identification, if possible, would be most appreciated. Best regards, Jack
This is a caterpillar (likely an arctiid) that has been parasitized by a wasp in the family Braconidae. The white objects are cocoons spun by the wasp larvae after they emerged from the caterpillar’s body. Judging by the detached ‘caps,’ most of the adult wasps already have emerged from their cocoons.

2988 Hi, I live in Northern VT in a house built less than 4 years ago. We have cherry hardwood floors and recently noticed sawdust around one of the knots in the floor. Upon closer inspection we pulled this guy out of the hole. It's back end was punctured in removing it, that is the reason it is so large. It appears to be a beetle larvae based on other pictures on this site. I was curious if this was something that could have been in the wood when it was installed or if it is something native that made it's way into the house. Also, should we be worried about it or is it most likely an isolated incident? Thanks, James
This is a larva of a beetle in the family Dermestidae (carpet/hide/pantry beetles and allies). Some in the genus Dermestes may construct hollows in wood prior to undergoing pupation, but they are not structural pests per se. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2987 I found this bug on my driveway. I live on an acreage just South of Prud'homme, Saskatchewan, Canada. It was about an inch and a half long. It was found on July 8th, 2010.

Without being able to see the end of the abdomen of this specimen, I am uncertain as to whether it might be a larva of a rove beetle (Coleoptera: Staphylinidae - see http://tinyurl.com/27prcfu for an example) or a snakefly (order Raphidioptera - see http://tinyurl.com/2eghrwa for an example).

2962 Hello Web manager, Although I assume this to be a moth of some kind, I would like to know if there's anything special about it. It has unusual coloration for a simple moth. It was about 3/4 inch long. I live in central Alabama. Thank you. Best regards, Jack
This is a tiger moth (Lepidoptera: Erebidae; subfamily Arctiinae, tribe Arctiini); likely in the genus Apantesis - see http://tinyurl.com/28g7kra for an example.

2958 Hi, We live in Dallas, TX and have a bug infestation that seems to be at one side of our property near the trash and a tree. The bugs are quite slow to react to us and can fly if needed but spend most of the time crawling on the ground and walls. Black/dark-gray on top with red markings, and light gray underneath. They are starting to enter the house, and although they appear harmless, they are in such large numbers since May. Thanks, Jon

2954 Found these two bugs in my northern Arkansas vegetable garden in late June on my Brussels Sprouts. I have been unable to find any info or identification for them. The orange one is about an inch and a quarter in length and the black one looked about three quarters of an inch long. Accept for their color and size they were very similar in physical appearance They appeared to be copulating when I first observed them, but could have been in a predatory or territorial dispute. Would like to identify them and determine if it they are beneficial or destructive. I am reluctant to kill bugs until I determine if they are friends or not. When I checked several hours later the black one was still around but the orange one was nowhere to be found. Thanks for any help...Lee
The orange insect is freshly eclosed adult wheel bug, Arilus cristatus (Hemiptera/Heteroptera: Reduviidae); the black one simply is the now empty exoskeleton of the final nymphal stage from which the adult emerged. These insects are general predators on other small arthropods, and thus usually are considered beneficial. Handle with care, though, they are capable of delivering a very painful bite if mishandled - see http://tinyurl.com/r3jvp7 for detailed information. Ed Saugstad.

2914 Hello, I haven't been able to identify this spider. I live in San Diego and this spider (and several of his friends) have been running around the house. They don't seem to have a web and are quite fast, running across the open carpet. I'm a little afraid it's a brown recluse, but the coloring doesn't seem right. Hopefully the picture is clear enough. I've put him in the freezer to maybe get a better look once he's dead. Thanks for any help, David
About all that I can say with any certainty about this spider is that (1) it is a male, and (2) it is not a recluse spider of any kind. It could be ground spider (family Gnaphosidae), but there are species in other families that can have a similar appearance. At any rate, it is nothing to worry about from a human health standpoint.

2910 Hey there! This bug was found recently in my garden in Georgia. It's not a pest, but I was hoping you could help me with identification. Any idea what it could be?? It's hairy and has compound-looking eyes, like a fly, but is eating a fly! It also has what look like cerci, which makes it look like an Orthoptera, but it's missing the strong hind legs! Thanks for any advice!

This is a robber fly (Diptera: Asilidae); they are general predators on other small arthropods, usually darting out from a convenient perch to nab their prey, then returning to the perch top dine in leisure.

2909 I live in Kincardine, Ontario. Every June these bugs appear, attack and destroy my roses, apples and peonies. They eat the flowers, young fruit and the leaves. Could you please tell me what they are and how to get rid of them.

Like number 2906, these appear to be chafers (Coleoptera: Scarabaeidae; subfamily Melolonthinae). As with their cousins, Japanese beetles, some chafers can be very destructive foliage pests. Any insecticide labeled for use against chewing insects should provide some measure of control. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2908 I am from 20km west of Innisfail AB. The last 3 years we have had a infestation of these beetles on our lilacs. They have damaged the trees, because of ?. They always appear just as the lilacs start to bloom, last year the lilacs had thousands of them on them. I have tried various spays, it causes them to drop to the ground but does not seem to kill them. The beetles are about the same size as ladybugs. Thanks, David

2901 I found this insect on the floor in my house. I picked it up because I at first thought it was an old grape or something my kids had left around, and when I flipped it over, I saw legs, which seemed to be curled up or tucked in somehow. Still believing the thing to be dead, I put it on the counter and went to fetch my husband. Upon our return the legs were extended. I live in southern Ontario, Canada, and it is early June; mid spring. It has been freaking me out a little as I hate having bugs in the house, and I have never seen anything like this thing before. I'm still not even sure if the specimen is alive or dead... Image one is the underside (I think) and shows the little legs and "face like" markings. Image two is from the top .. Help!
This is fully engorged female hard tick (family Ixodidae); likely in the genus Dermacentor. See http://tinyurl.com/26r6qdc for an image of engorged and unengorged ticks. Your specimen likely dropped off its host after feeding, and was looking for a place to lay its eggs. You should destroy it if you have not already done so; and if you have dogs or cats as pets, check them carefully for the presence of ticks. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2899 My husband and I noticed this spider by our front porch light at our apartment building. We live in North Texas. I'm hoping someone can help me identify it. We actually find different spiders quite frequently outside our front door. We first noticed it at night time and it stayed in the same place all night and day. The second picture is after, I'm assuming, one of our neighbours killed it. I am somewhat fascinated by spiders and am just curious as to what kind this one was.

2898 This is the 2nd year that I have lived in my house near Sacramento, California. I purchased the home right after it was built. Both years at around this time a ton of beetles start coming out onto my floors. I think it is some kind of ground beetle. I have looked all of the internet to find out what they are, but the closest thing I found was the Harpulus Ground Beetle. I just am not sure what exactly it is. Thank you for any help you can give. Nathan
This does appear to be a ground beetle (Coleoptera: Carabidae) and could very well be in the subfamily Harpalinae (see http://tinyurl.com/2cwh62l for an example); but this is an extremely large and variable group and I cannot offer a specific identification.

2897 I saw this bug out in front of my apartment in San Angelo, Texas. It is bright green on the front of the body, and brown on the back of the body, there is also some brown spots near the front where the wings are connected. The whole body is about 1 inch, the wings are translucent with a little green on the "veins" near the body. The wings are about 1 1/2 inch, and it appears injured right now. It appears to have two protruding "bug eyes" as opposed to a traditional fly type eye. I have been in some jungles, and this is the weirdest looking fly-type bug I have ever seen. 2 or 3 times the size of a horse fly at minimum. What is this thing?
This is a cicada (Hemiptera/Auchenorrhyncha: Cicadidae); there are some 40 species of these insects reported from Texas.

2869 This composite picture was taken from our window at the Toronto Harbourfront on May 28 at around 6 a.m. I am assuming that both mosquitoes belong to the same species, the one on the left with the bushy antennae being male and the one on the right being a female.

Is this species of mosquito a carrier of the West Nile virus? I have enjoyed very much visiting your website since discovering it a few days ago. Many thanks Ara

These are non-biting midges (Diptera: Chironomidae), and you are correct in their sexes.

2862 May 2010, Quebec. Found in a bedroom closet; white; 6 legs; approx. 3/4 of a centimeter; looks like a cross between a spider and a cricket.

This is a nymph of an assassin bug (Hemiptera/Heteroptera: Reduviidae) known as the masked hunter (Reduvius personatus). See http://tinyurl.com/36am447 for an image and http://tinyurl.com/mwq56m for detailed information. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2861 Hi, I found a pair of these flying bugs last week in our well-lit downstairs bathroom in our old house. We've been here 6 years, and have seen most bugs known to mankind, but we've never seen these bugs before. I just found another single one today. Could you please identify this bug for me and suggest a course of action? From photos that I've seen, I'm concerned that they are flying termites. Thank you. Merle, Dundas, ON

I cannot be absolutely certain, but this looks like a member of the family Heleomyzidae - see http://tinyurl.com/29pbt8g for an example. These flies are harmless; their larvae are scavengers on decomposing organic matter, there is no need for control. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2860 Hi. I'm in Northwich, North - West UK. We had a very hot spell lately (25 - 30 * C) and all of a sudden these started appearing. My friend scared me saying they might be American cockroaches. They're mostly in the living room and we find them during the day - they're not afraid at all and they don't run away. Lately one of them was found in the bathroom as well. What are they? Any ideas please? Thanks, Brian

This is a beetle known as a wharf borer (Nacerdes melanura; Coleoptera: Oedemeridae) - see http://tinyurl.com/2dqfwft for an image. The larvae may be found in moist timbers, such as wharf timbers, foundation pilings under buildings, in damp cellars or crawl spaces, in wood around leaky faucets, in buried wood, or in any wood that is damp or soggy, and particularly if it is decayed. They do not appear to attack sound timber. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2859 Found this guy on the ladder to our in-ground pool in Massachusetts. I thought he might be a fishing spider because seems to resemble them the most based on the pics I've seen, but not quite as furry as the ones I'm seeing on this site. It is at least 3 inches in diameter. Also, I was almost positive I saw a spider just like this sitting at the bottom of the pool last year but thought it had to be impossible, but now that I've seen this one up close and have read that fishing spiders can hang out under water for 30 minutes I'm thinking I had been right. Is this a fishing spider?

This is indeed a fishing spider (family Pisauridae); likely Pisaurina mira - see http://tinyurl.com/onwnr7 for an image. Large specimens can deliver a painful bite if mishandled; they otherwise are harmless to humans. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2858 Here is a photo of a ??? I found while gardening. It was in the ground about two inches from the surface. Only it's rear part seems to move but not often. What is it? The photo was taken near Joliette QC about 50 Km north of Montreal. It was taken on May 25th 2010, full sunshine, 35 Celsius, outdoor, in my garden near a stone walkway. It measures about 2.5 mm X 8mm dia. Thanks, Clement

These are moth pupae, but it would be nearly impossible to tell exactly what kind without microscopic examination. My best guess is that they may be in the family Noctuidae, as many of these pupate in soil litter or beneath the soil surface. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2857 Hi, I live in Toronto in a basement suite and just found this guy flying around my bathroom. I also recently saw an already dead one in my kitchen. It is about 5 mm long. It's the end of May and has been quite hot and humid lately. Should I be concerned about these little creatures, or are they harmless? Thanks, Kayla
Although I cannot provide a positive i.d. for this moth (that would require dissection and microscopic examination), it does not appear to be any species that would be of concern from an indoor pest standpoint. The only really tiny moths apt to cause problems indoors are clothes moths (family Tineidae), and their wings look different from those on your specimen - see http://tinyurl.com/28g6s35 for an image.

2856 Hello, This insect has been lurking around my apartment. I've found 4 in the past 3 days. The location is Halifax, Nova Scotia. The apartment is on the 11th floor of a 14 story building. Two were found in the bathroom and two in the bedroom. They were found indoors on the floor, in the late spring/early summer of the year. The are about 3/4 the size of a dime in length (6-7mm roughly). They are very quick when startled. I'd love to find out how to get rid of these! Thank you, Mick

This is a bristletail, a primitive insect in the order Thysanura. Some species, such as silverfish and firebrats, can be nuisance pests indoors; see http://tinyurl.com/cmar94 and http://tinyurl.com/23hmrd4 for images and more information. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2855 I work at a garden center in Fergus, Ontario and I found this guy on top of our water cooler in the annual house. I'm just curious what it is, it looks almost like a type of lady bug.

These appear to be young nymphs of the Florida predatory stink bug, Euthyrhynchus floridanus (Hemiptera/Heteroptera: Pentatomidae). They are general predators on other small arthropods. See http://tinyurl.com/2asggnh for detailed information. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2850 I Bought some Garden soil " Miracle Grow " first time I ever used it and these things started to come a couple every couple day's what are they? it has a Hard Tail section a hairy body it has yellow strips on it's legs and antenna, But the dam thing has two stinger's According to the bag it came from FL. if that helps at all. Should i be worried? I'm allergic to bee stings . I have a sample of the damn things. ~ Jim

These are wood wasps known as horntails (Hymenoptera: Siricidae); the ‘long ‘stinger’ is its ovipositor, used to insert its eggs into the wood in which its larvae develop, They have no venom and are harmless to humans, and the association with the garden soil is strictly coincidental. Your specimens appear to be Urocerus albicornis (see http://tinyurl.com/2bx4mn6). Ed Saugstad. Retired entomologist; Sinks Grove, WV

2849 My husband found this bug in our back yard, we live in Central Newfoundland and have never seen a bug like this. Someone said it looks like a giant water beetle. Still we have never seen anything like this before in our area. It was a chilly damp day. It was found on May 20th. Thank you, Debbie

This is a giant water bug (Hemiptera/Heteroptera: Belostomatidae); an aquatic predator and very strong flier. See nos. 2824, 2810, 2804, and 2773 for other examples. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2848 Hi, I live in Austin, TX. I heard my 4 yr old screaming outside and when I got to her this little booger was crawling up her leg. When it's stretched out it's about 3 inches long. It's showing what seems to be yellow antennae coming out of what I think is it's mouth. I was just curious as to what was crawling on my baby. Thank you for your help. We found it in the middle of May. Kara

This is a caterpillar of a tiger swallowtail butterfly (Papilio glaucus; Lepidoptera: Papilionidae) - see http://tinyurl.com/2fyuhq9 for detailed information. The yellow ‘antennae’ actually is a defensive organ known as an osmeterium - the caterpillar uses it to emit a foul-smelling chemical to deter predators - see http://tinyurl.com/2f96qgq. Ed Saugstad.

2847 Hi! I recently found these little 'beetles' on my false spirea plants. they are destroying them! the flower buds have wilted and so have some leaves. they are only about 3 mm long but they don't seem to be aphids, I compared pictures already. please help, my plants are dying! thank you so much!

This is a young nymph of a plant bug, likely in the family Miridae. One member of this family, the tarnished plant bug (Lygus lineolaris) has been reported as a pest on false spirea; see http://tinyurl.com/2akhyf3 for images of nymphs and adults of this species and http://tinyurl.com/26hv8me for a fact sheet that includes control recommendations.

2846 Hi, We found these insects on our grapevine. They are about 5mm in length and run up and down the stalks of the vine. The infestation has lasted since the beginning of hot weather in May (around 30 degrees C) here in Beijing, China. They tend to cluster at the end of the stalks, and under the leaves. We have also noticed tiny, round, clear ´spheres´ of some kind of liquid or secretion, but we're not sure if that's associated with the insects or not. We'd be very grateful if anyone could identify them for us! Many thanks and regards, Nic & Andrew

These are planthoppers in the family Fulgoridae; members of this family often have a very bizarre appearance and usually do little real damage to their host plants. The shape of these is similar to that of the genus Lycorma that is native to China - see http://tinyurl.com/22u6dvg for an image. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2845 Hi, just wondering if you could tell me what this interesting insect is called? It was dig holes in a small hillside at our cottage in South Hampton, New Brunswick. Thanks! Melanie and Derrick Fredericton, New Brunswick.

This is a blister beetle (Coleoptera: Meliodae) in the genus Meloe - see http://tinyurl.com/22qxkv7 for an example. Beetles in this genus sometimes are called oil beetles; when handled roughly, they will ‘bleed’ reflexively from their leg joints. This fluid (haemolymph) contains cantharidin, a chemical that can cause blistering of tender skin. See http://tinyurl.com/y2u2sck for more detailed information. Ed Saugstad.

2841 I'm am in Montreal. I found this little thing alive on my bed skirt. I’ve had some red plaques on the skin lately (one per 2-3 days) and think this thing might have bitten me?? I looked hard and found nothing else. It was alone by itself. It’s about 3mm long and almost completely flat.. I think it only had 4 legs, but it might be 6 as well... they broke off when I removed it from the skirt (it didn’t wanted to let go. Thanks, P-L

Although this is a true bug (Hemiptera; suborder Heteroptera), it does not appear to be a bed bug - see http://tinyurl.com/2drlaon for a ventral view of one. Unfortunately, I cannot provide a definitive i.d. from your image; a dorsal view, preferably undamaged, would be necessary. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2840 All of the carpet in my house is full of these bugs - the front ones look like larvae and the back ones are the adults. They have one light colored stripe diagonally across the top of their body. The larvae are hairy. All the pictures I could find online of carpet beetles appeared much rounder in shape than these little oblong guys but otherwise they seem to fit the description. The vacuum doesn't get them. I am pregnant and also have three small children so I am not keen on using pesticides. Are these in fact carpet beetles? And if so, how do I get rid of them?

2839 HI, I found this beauties near the picnic table. We live in central MN. They look to be two different types, are they orb weaving spiders? Aaron

The spider on the left is a wolf spider (family Lycosidae); these are active hunters that do not spin capture webs. The spider on the right is a comb-footed/cobweb spider (family Theridiidae) in the genus Steatoda. Although not dangerous, either of these can deliver a painful bite if mishandled. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2838 This bug practically decimated my cotton Easter hedge . It appears to lay tiny black eggs, almost like black dots of dust, on the underside of the leaves. Seems to suck from the leaves, the leaves turn shiny , sort of sticky. Then the next spring everywhere they were is dead. Can you tell me what they are, and how to get rid of them, before they completely devastate.

2837 I found this bug in my firewood. I believe it is hickory and there. Holes, sawdust and small tunnels on wood. Photo is after death. If any of this wood gets stored inside are these bugs going to be a problem. Thank you, Ron. I am in Jamestown NY.

This is a long-horned wood-boring beetle (Coleoptera: Cerambycidae) known as a painted hickory borer (Megacyllene caryae) - see http://tinyurl.com/23mso27 for an image.

2835 Hello, These tiny crawling specks have recently invaded the bathroom at a wall in close proximity to a birds nest on the outside wall. Perusing the entries it would appear these are mites, reasonable assumption? It makes sense that removal of the nest is the first step toward mitigation, what else is recommended? Is it safe to assume these are more of a nuisance than a threat? Great site, thanks! Curtis, Oregon

2831 I find clusters of these insects on my chili plants every spring. I live in Guanajuato, Mexico. Despite being very different in appearance, I suspect that pictured are two stages of the same species. Are they harmful to the plant? If so, how may I control them and not harvest toxic chili peppers?

These are nymphs and adults of treehoppers (Hemiptera/Heteroptera: Membracidae); these are sap feeders that with a few exceptions, seldom cause serious harm to their host plants. If they appear to be harming yours, you could try applying organic controls such as neem oil or an insecticidal soap. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2830 I need some help. This bug has popped up in the number of hundreds of thousands across my property. They cover the parging on my house, my driveway, sidewalk, and sandbox. Everywhere warm. They are 2-3 mm big. I live in Stony Plain, Alberta. Thanks.

The image is not clear enough to be certain, but these have the general appearance of broad-nosed/short-snouted weevils (Coleoptera: Curculionidae; subfamily Entiminae) - these primarily are root feeders as larvae. However, if they are these weevils, their antennae should be more prominent.

At the same time she suffered four bites which over the period of a week have gone from small blisters to open wounds to scabs, but the inflammation has increased in intensity over this period.

This is a hard tick (family Ixodidae) in the genus Dermacentor. These can vector diseases including Rocky Mountain Spotted Fever (see http://tinyurl.com/2b4r8xk), but the tick apparently must remain attached for at least 24 hours before there is significant risk of transmission. Any arthropod bite can become inflamed through secondary bacterial infection; this does not correlate with disease risk from the arthropod itself. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2811 We found this monster in the bathroom sink on the 2nd floor of our house in Auburn, California (Sierra Nevada foothills, 30 miles from Sacramento, CA). We spent all night trying to convince ourselves it is NOT a drywood termite. We just brought home a dry sauna from my brother's house in Santa Cruz, CA. He had/has drywood termite problems Can you please tell us what this is? I love the fact that you help out non-entomologists with entomology. Thank you!!

Given its large size and dark wings, this more likely is a dampwood termite (Zootermopsis sp.) - see http://tinyurl.com/27dm39g for an image and http://tinyurl.com/28kxn2h for a detailed fact sheet that includes control and preventive measures. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2810 I Live in St. Johns, NL Canada, I Found this bug on my door step. Very frightening because of its size, It looks like some kind of beetle that can fly, it has some kind of snappers on the front of it, almost like a scissors, and has like a stinger at the back. I have only seen these bugs at night. Any help or information that you can give would be great. Thank You Tina

This is a giant water bug (Hemiptera/Heteroptera: Belostomatidae), a voracious predator on other aquatic invertebrates as well as on tadpoles and small minnows. See no. 2804 for another examples and more information. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2809 I'm from MN USA and have found these in my carpet and on the walls Inside my Apartment. they look like sow bugs but I have no moisture problems or any plants.-Aaron

These are indeed sowbugs. Even though you may not have a moisture problem in your unit, is it possible that there are moisture sources immediately adjacent to you? Ed Saugstad. Retired entomologist; Sinks Grove, WV

2808 These bugs were found in Fresno, CA in the inside of a house. There were a lot of them. Nicole
These beetles are in the family Scarabaeidae; likely in the subfamily Cetoniinae (fruit and flower chafers) - see http://tinyurl.com/276m9py for an example. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2807 I found this insect in a UV fly trap, can you please help to identify this insect? Thank you, Lallini

This appears to be a Asian moth in the subfamily Arctiinae (family Erebidae) known as handmaiden moths (Amata sp.) - see http://tinyurl.com/yjw5uhg for an image. Many of these moths mimic wasps in their appearance. As has been mentioned several times before, it really helps if the geographic location for the imaged arthropod is specified. Ed Saugstad.

2806 These winged insects plague my kitchen every spring and summer. Boston Massachusetts. Any ideas what they are or how I can get rid of them? Lou

These are Indian meal moths (Plodia interpunctella), a very common and widespread pantry pest. See http://tinyurl.com/d5pu6j for a fact sheet with detailed control recommendations. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2805 I found this spider in my garage in a pile of firewood today. I live in Dallas, TX.

This is a cobweb/comb-footed spider (family Theridiidae) in the genus Steatoda; most likely Steatoda triangulosa - see http://tinyurl.com/ydck5e2 for an image. Although this spider belongs to the same family as the notorious black widow spider, it is harmless to humans. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2804 I found this beetle in my flower bed last night. I came late at night and I could hear it making a noise and it appeared to be sucking into the clay. What is this insect. it is about 2 inches long and 1 inch wide, before it spreads its wings. Anyone that can help me identify what it might be, please reply. It does resemble a water beetle that was occasionally seen on some farms during the hot summer years ago, but it is still cold here. Ann

This is a giant water bug (Hemiptera/Heteroptera: Belostomatidae), a voracious predator on other aquatic invertebrates as well as on tadpoles and small minnows. They are strong fliers that can be found quite some distance from water. Live specimens should be handled with care, as they can deliver a very painful ‘bite’ with their beak. See nos. 2751 and 2773 for other examples and http://tinyurl.com/yehfmw for more detailed information. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2803 Hi there, I recently moved into a new apartment and I keep finding these bugs in the kitchen. They are approximately 3-4mm in length (very small) and I see approximately 6 a day. They are easy to kill and I have sprayed Raid a few times in the evenings and wake up to a few dead on the floor but they keep coming back. Would love to know what they are and if I should be concerned. I am an extremely tidy person and clean constantly so I’m not sure why there coming back.. Thanks, Shari

This is a cockroach nymph, likely that of a brown-banded cockroach (Supella longipalpa) - see http://tinyurl.com/25xtygj for a fact sheet. Cockroaches can present a serious control problem in large apartment complexes, as they readily move from unit to unit, and full control thus hinges on a cooperative effort involving all tenants as well as management. Ed Saugstad. Retired entomologist; Sinks Grove, WV

2802 Hello, the attached photo shows some insects I have never seen before. Some of these were actually moving. I had recently termite treatment, could these be termite larvae? Thank you so much for your help. Jozo

It is difficult to be certain, but this appears to be a now empty case constructed by a small caterpillar. Depending on where you live (please specify your geographic location when submitting images), this could be a nuisance pest known as a household casebearer (Phereoeca uterella; Lepidoptera: Tineidae) - see http://tinyurl.com/dn4jn5 for detailed information.

2801 I have found two of these bugs in two days in my house in Texas...both in the bed. I think it's a kissing bug. I am worried about Chagas disease! What is this bug and why is it in my bed?

This is indeed a nymph of an assassin bug (Hemiptera/Heteroptera: Reduviidae) in the genus Triatoma; possibly Triatoma gerstaeckeri, a potential vector of Chagas’ disease - see http://tinyurl.com/2cuvqr8 for a detailed article. Ed Saugstad. Retired entomologist; Sinks Grove, WV
