Larva (Rodent Bot fly)

#5475  This was found on my laundry room floor in Boulder Colorado just now.  It’s a little over an inch long, dark brown and ringed, with a yellowish “nose.”  It’s creeping very slowly.  What the heck is this?
This is a mature larva/prepupa of a rodent bot fly (Diptera: Cuterebridae; Cuterebra sp.) – see for images and more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.


5645 My name is Charlotte. This bug was found in Vanderhoof British Columbia.  I found this bug in my bathroom where swallows have gotten in and built a nest in the fan ducting above. They might be gone now as I can’t hear them.

This is a weevil (Coleoptera: Curculionidae); it looks like a member of the subfamily Entiminae (short-snouted/broad-nosed weevils). These often enter buildings in search of shelter, but do no harm there. I doubt very much that there would be any association with the swallow nest. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Larva of Dermestidae Beetle

5644   hi there we have found a bug on our wall and just a day or two before we have found this bug we have been getting some sorts of hives on our skin like mosquitoes  they itch once in a while. We saw a doctor and he didnt know what it was than today we found a bug which had this hairy type thing in th eback we took a picture hopefully you can help us find out what it is.

This is a larva of a beetle in the family Dermestidae (carpet/hide/skin/larder beetles and allies); likely in the genus Anthrenus.  Some people have reported skin irritation from exposure to the hairs on the bodies of these insects, but that appears to require long-term exposure to a heavy infestation. Nevertheless, you might consider an appointment with a dermatologist/allergist. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Definitely not a bed bug

5643   Pls see photos attached. I live just outside of Vancouver ,in the Lower Mainland. The other day,  I found a dead bug in the corner of my son’s bed, in between the sheet and mattress cover.   It looks like it has been dead for some time. I am worried sick that  it is a bed bug. I also found a flea at the same time. I’m horrified. We just moved into a upper floor of a three bedroom home. As soon as we moved in,  my son started to get bit on his lower left leg. Big welts that were very itchy and made worse with the scratching.  He never had any bites in our old home where we lived for 13 years. So after he got these bites,  that is when i looked in his bed and found this one dead bug and one flea. (I’m wondering if he got the flea from the long grass outside. We never had fleas or bites before).  I kept this dead bug under a glass. I need someone to please ID it for me before I go crazy. We have torn apart the beds looking for anything. We have not found a thing. No black marks,  no bugs at all. I’ve spent hours researching on the net,  so I know what to look for. There were some small blood smears on his white comforter but he says that he picks at things! Even took off the gauze under the box spring. ..nothing. we’ve only been in this house for a week.  Thanks very much, Leslie

Definitely not a bed bug; this poor creature has lost so much of its appendages as to make a positive identification problematic. Among the possibilities is a silverfish (Zygentoma: Lepismatidae), these are harmless nuisance pests that would not be responsible for any bites. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Leaf-footed bug nymphs

5642  I live in Edenglen, which is very near to Johannesburg, South Africa.  We are nearing the end of our summer season.  This was photographed yesterday.  I have a bush in my garden that is now has hundreds of these bugs (pic attached) all over it.  I have never seen them before and I am very interested to know if this bug is harmful to plants and what my actions should be with regards to them.  Should I destroy them or the bush or are they harmless?  Kind regards.  Louise

These are nymphs of a leaf-footed bug (Hemiptera/Heteroptera: Coreidae); they look like a species known as the giant twig wilter, Carlisis wahlbergi. See for an  image and for an image of an adult. They do not appear to be considered as serious pests.   Ed Saugstad, retired entomologist; Sinks Grove, WV.

Sphinx moth

5641 The attached was photographed off the west coast of Mexico in December 2015. Can you help with identification? Thanks, Howard

This is a sphinx moth (Lepidoptera: Sphingidae), but it has lost too many scales to be confident of a specific identification. Ed Saugstad, retired entomologist; Sinks Grove, WV.

folding-door trapdoor spider

5640   I live in Kelowna bc and I accidentally killed the one that’s all scrunched up. Then this other guy showed up and I’ve searched and searched for his species and can’t find it anywhere. He is about the size of my thumb. Thanks in advance.

This looks like another folding-door trapdoor spider (family Antrodiaetidae); see no. 5638. Ed Saugstad, retired entomologist; Sinks Grove, WV.


Camel Cricket

5637 My name is Michael.  I live in Long Island New York. I Have many of these bugs in my house.  They started appearing in September 2015. They jump really high.  They are about one inch long.  Help..What is it and how do I get rid of them.

This is a camel/cave cricket (Orthoptera: Rhaphidophoridae).  These sometimes also are called ‘sprickets’ because of a fancied resemblance to a cross between a spider and a cricket. They basically are nuisance pests that do little if any real harm. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Moth Larva (caterpillar)

5636 My name is Andrea Moretz.   These are very tiny bugs that are on my sun lamp shade. The other picture is a picture of the what I assume is eggs also on the lampshade there are two clusters about the same size.  The bug is so tiny I would say it’s smaller than the size of a pencil LED. I live in a desert area that is very hot and dry although we did get rain this week. In the southern region of California in the United States.

This appears to be a newly hatched larva (caterpillar) of a prominent moth (Lepidoptera: Notodontidae) in the genus Furcula, see for a slightly older specimen. Moths often lay eggs in odd places when they find themselves trapped indoors at a time when they must lay their eggs. Your larvae will quickly starve, as there will be no suitable food source for them indoors. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Click Beetle

5635   This bug was found crawling across the floor of my living room.  I live in the rural area of Osoyoos, BC. The weather today is cloudy and 10 C. The insect is a 1/2 inch in length. Would appear it has 6 legs and no antennae that I can see. The back appears to be brown or copper with black in colour, the head would appear to be black and is divided down the middle. It appeared to jump when pressure was applied to it’s back. I have not observed this insect in my home before. I have been outdoors lately hiking in the sage country so am unsure if it came in on my clothing or has been present in my home.  After further observation the bug does have antennae and does jump on its own and has 6 legs.  Thanks. Ken

This is a click beetle (Coleoptera: Elateridae). It is completely harmless, and may be ignored. Ed Saugstad, retired entomologist; Sinks Grove, WV.

long-horned wood-boring beetle

5634  Please help me identify this insect. I found it in my house Kitchen floor and on walls. They only show up one or two at a time.  Location: Waterford, CT.   Thank you,   Joyce

This is a long-horned wood-boring beetle (Coleoptera: Cerambycidae); it looks like a Megacyllene sp. (locust borer and allies). They will not infest timbers or anything else in your house. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Predaceous diving beetle

#5633  Hello, Hoping to identify this bug please. caught April 1, 2016 at dusk (about 8:30pm) west edge of Calgary, Ab.   Canadian quarter for scale.  Cat caught it in garden mulch near coniferous trees.  Thank you, Carol

This is a predaceous diving beetle (Coleoptera: Dytiscidae); likely in the genus Dytiscus. These beetles (and their larvae, ‘water tigers’) are general predators on other small aquatic life forms. They also are excellent fliers, and may be found quit  some distance from any water. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Click Beetle

5632   Found this guy in a piece of rotting wood in panhandle north Idaho.   Jeff 

This is a larva of a beetle, possibly that of Alaus oculatus, a click beetle (Coleoptera: Elateridae); see for an image. These larvae are predaceous on other insects found in rotting wood or under bark of dead trees/logs. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Sow Bug

5631       We found these bugs all around our garage tonight. It is very obvious that they were hiding around boxes left in the garage over winter. Now that spring is here I found them inside the garage and some around the outside if the house. My brother and friend are telling me they are silverfish and are very hard to get rid of and for the moment are contained out of the living area but we are quite concerned about these bugs getting indoors.  I live I’m Edmonton and it’s been warming up to spring like conditions for the past couple weeks already. The garage areas we noticed were dark and damp. Your assistance would be greatly appreciated in identifying and suggestions of how to control these bugs. Thank you.  Dearl

This is a terrestrial crustacean in the order Isopoda, possibly in the family Oniscidae. Isopods are known by many common names, including wood lice, pillbugs, sowbugs, roly polys, slaters, etc.; nearly all are harmless scavengers on decomposing organic matter, and will cause no damage. They breathe through gills that must be kept moist, so keeping indoor humidity levels low will discourage them from setting up housekeeping. Ed Saugstad, retired entomologist; Sinks Grove, WV.


#5630  My name is Lisa. I live in Calgary, Ab. We have had a very mild, dry winter and an early, dry spring. The gophers are out and my dog has been sticking her head down their holes. Within a few days I noticed one of these bugs crawling in her fur. It was hard to kill (simply squishing didn’t do it). Then I found one hopping and crawling in our bed. Our dog sleeps with us. The next morning I found another one in our bed where she sleeps and I had two areas on my arm with small clusters of itchy little bites. My husband has also been bit a time or two. And I have since found a couple more on my dog. She is being treated for fleas and I have vacuumed like crazy, done a million loads of laundry and spread salt everywhere. I have not seen anything more in at least 5 days. The critters that I did catch when put into a pill box jumped around madly. My vet says it’s not fleas as they have wings. What else could it be? My understanding is that bed bugs don’t jump and they don’t have wings either.

These are fleas (order Siphonaptera); likely in the genus Ctenocephalides. If your veterinarian saw wings, they either were very mistaken or were looking at something other than a flea. In addition to consulting a veterinarian, you can find control advice at elsewhere on this site. Ed Saugstad, retired entomologist; Sinks Grove, WV.


Biting bug in bed

#5628  I found this bug in bed biting me. Obviously indoors in spring time (March). Its small about 3mm big or so. In ottawa Ontario.   Ginette

Biting? In bed? It seems that you have bed bugs (Hemiptera/Heteroptera: Cimicidae; Cimex sp.). See elsewhere on this site for control advice. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Boxelder Bug invasion

# 5627  Can you tell me what these bugs are? They are all over our apt building. We have never had them here before. Thanks.

This is a Boxelder bug.  For more photos and information see our web page:


Moisture Ant

5626  Hi these just showed up today on the side of my house. Thousands. So thick i can sweep them with a broom. They look like ants but have wings. Can you figure out what they are. Thanks. David. Toronto. 

This is an ant, possibly in the genus Lasius (- see for an example (this one formerly was placed in the genus Acanthomyops, now considered a subgenus of Lasius). Many Lasius species, known collectively as “moisture ants” in the United States, make their nests in and around moist rotting wood as well as under rocks, but are not considered structural pests. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Dermestidae Beetle

5625  Hi, these photos were taken in downtown Toronto in my condo. It’s winter, but I’ve seen these bugs in different seasons. I’ve only seen them a handful of times and only on the floor. They are only ever these tiny little things that I can barely see.  What is it?! Do I need to fumigate?!   Thanks.   Gillian

This appears to be a beetle in the family Dermestidae (carpet/hide/skin/larder beetles and allies). No need for fumigation, but you probably should check any dry stored food products for signs of insect infestation. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Stink Bug

5624   Hello,  I found your site and looked through your photos and could not identify one that matches what we have. These are in our home, I have killed over 25 of them since moving in aprox. one year ago. The length is 5/8 in long x 3/8 in wide and they do fly. I have generally found them when we have a change in temperature/ warmer day. I live in Plymouth Michigan, which is a suburb of Detroit. Please let me know if you can help.  Thank you.  Ronald

Like No. 5621, this is a brown marmorated stink bug, Halyomorpha halys (Hemiptera/Heteroptera: Pentatomidae). Ed Saugstad, retired entomologist; Sinks Grove, WV.


5623   Hello,  I have found a few of these tiny bugs in my bathroom recently and while I am usually not afraid of, or grossed out by insects, this one looks particularly creepy. It is small; only 1/4″ long; jet black in colour, has 8 legs and 2 disproportionately large pincers of some sort extending out from its head. It did not move while I was observing it so I cannot speak to its movements. I live in a detached, fairly new build house just outside of Sarnia, Ontario. Could you please help to identify this insect and let me know if it should worry me or not? Your help is greatly appreciated! Thanks so much!! Regards,  Lana

This is not an insect, but is an arachnid called a pseudoscorpion. They are general predators on other mall arthropods and completely harmless to humans. See for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

True Fly

5622    Hi,  I work outside at works yard and I come across a lot of bugs and especially mosquitos (Pemberton, BC). I’ve just noticed them coming back around but noticed the past 5 or 6 of them are all black and not the usual brown colouring you find here. Can’t find any white spots or stripes that would possibly make it a (Asian) tiger mosquito.

This is not any kind of mosquito, but does appear to be a true fly in the order Diptera. Unfortunately, the condition of the specimen as well as the lack of clarity in the image precludes a more definitive identification. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Brown Marmorated Stink Bug

5621  These are about 1.5cm long, moves very  slowly, you can poke it and it won’t mind, can fly but do so rarely. It’s brown despite the picture, they look identical to eachother.  Enjoys moisture, often found near faucets and certain old window frames, I’m assuming it eats wood because my house is old and it doesn’t swarm on food.  I’m on the border right by Niagara Falls.  It smells absolutely terrible when crushed.  Any idea?

This is a brown marmorated stink bug, Halyomorpha halys (Hemiptera/Heteroptera: Pentatomidae), an introduced species that is both a potentially serious orchard pest and a nuisance pest when large numbers invade buildings in search of shelter. See for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Stink Bug Carcass

5620     Hi my name is Angela and I’m from Conyers ga, found this strange looking creature under my bathroom sink.Can you please tell me what it is?  Thanks in advance.
This is a very dead stink bug (Hemiptera/Heteroptera: Pentatomidae) that has lost all its appendages (legs and antennae).  Stink bugs are not usually found indoors, but some, like the brown marmorated stink bug (Halyomorpha halys), can become nuisance pests when they invade buildings in search of shelter. Ed Saugstad, retired entomologist; Sinks Grove, WV.  


5619  Saw this guy today on Vancouver Island in Qualicum beach. Was about 8 degrees and partly overcast. He was on a large granite boulder that is covered in lichen and moss.   Maybe 1/3 centimeter in length. Scarlet red. Thought a spider because 8 legs but looks like a tick. But has a long proboscis and antenna?  Very interested to know what this little guy was.  Thank you! – Tanya
A puzzler! I first thought that this would be a giant red velvet mite (family Trombidiidae), but on enlarging the image, I could see that its body shape and texture were wrong for that. I now believe that this is Neomulgus littoralis, a snout mite in the family Bdellidae – see for an image. These mites reportedly use their sharp mouthparts to suck the bodily fluids of kelp flies. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Long Horned wood boring beetle

5618     Good Morning,   I found this bug in my kids bedroom crawling across the floor. Could you please identify for me?  Is it harmful? Thanks.
This is a long-horned wood-boring beetle (Coleoptera: Cerambycidae) in the genus Monochamus. Known as sawyers, some species in this genus can be serious timber pests, but unless you count being nipped by their strong jaws, they are harmless to humans. Ed Saugstad, retired entomologist; Sinks Grove, WV.  

Predatory stink bug

   5617           The bug in question is the top one. Found in Southern Ontario (rural Wellington area) in mid July/14. At the time, this was one of a very few I had seen in that year. Last year, they were quite common. It is approximately 1 cm in length, has six legs, and a poker that comes out of its oral region. This photo was taken while this bug’s poker was stuck in the black bug. The black bug could not get away. Both these bugs were found on my camping tent. The general area is heavily wooded with, I believe, Norway Spruce.  I have tried to identify this bug since this picture was taken. Any information would be wonderful. Melinda
This is a nymph of a predatory stink bug (Hemiptera/Heteroptera: Pentatomidae) in the genus Podisus; see for an image. Called soldier bugs, they will feed on just about anything they can overpower; yours is feeding on the larva of a lady beetle. Ed Saugstad, retired entomologist; Sinks Grove, WV.


5616  Hello, my name is Abby. I took these inside my bedroom, in Tennessee. I’ve seen about 3 of these over the 2 months I’ve lived here. I’m worried because they look like a cockroach but the place is very clean I can’t imagine how they got here. please help! Also the picture makes it look a little bit darker than the actual color of the bug.

This is a cockroach, but I cannot be certain of a specific identification. It might be one of the so-called wood cockroaches (Parcoblatta sp.) that are widespread in North America. These often get indoors, but usually do not set up permanent housekeeping there. Also, the presence of cockroaches is not in itself an indicator of dirty/unsanitary conditions; they are the ultimate opportunists. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Mud nest

 5615     I found this larvae in a mud tube under my fascia on the brick wall. I have these tubes at the front and the side of my house. At the front it looks like spiders but not sure at the side. I do get a lot of wasps around my house in July and August. This was taken Feb 20 2016 in Rockwood Ontario. Thanks Paul.
This is a mature larva/prepupa of a mud-dauber, a wasp in the family Sphecidae. It likely had consumed all the provisions (usually living but paralyzed spiders) that its mother had placed in the mud ‘nest’ for it. Ed Saugstad, retired entomologist; Sinks Grove, WV.



Western Conifer Seed Bug

Here are some better photos than the previous I sent. Found in Feb on warmer day.  I  wondered if it was leaf legged bug? As long as not harmful to health for folks with weakened immune system we’ll manage, in the meantime we are trying to sort out where our infestation of ladybugs  and these are coming from (same room).  They would go towards the light and showed up during the summer/fall months. Thanks for any input!  Niki.  Listowel ON
This is a western conifer seed bug (Leptoglossus occidentalis; Hemiptera/Heteroptera: Coreidae); it is a nuisance pest, especially when it gets indoors, but is harmless otherwise. Ed Saugstad, retired entomologist; Sinks Grove, WV.



Future Queen Ant

5613   I have attached a pic of an ant (there are more than just this one). Found inside home, early March, Valley, Nova Scotia.  Would really appreciate your help in identifying this as we are concerned that it could be Carpenter ants.  Thank you. Valerie
This does look like a queen carpenter ant (Camponotus sp.). See elsewhere on the pestcontrolcanada site for some control recommendations. Ed Saugstad, retired entomologist; Sinks Grove, WV.


5612  I find at least 3-4 of these slithery bugs in my basement bathroom every wk, depending on weather. I am located in the GTA (Toronto, On) they look black and alien like in person, but as I took a picture they don’t look as scary. They still move very fast. Ty
This either is a silverfish (Lepisma saccharina; Zygentoma: Lepismatidae) or a very close relative, basically nuisance pests that do little real harm. See for images and more detailed information.  Ed Saugstad, retired entomologist; Sinks Grove,

Common Cockroach

5611  Found this critter in our hallway in Toronto (Feb. 28). It’s very lively! It’s about 1.5cm long, not counting the antennae (which are themselves a little longer). It’s been below 0 outside for a few days now, but was warmer before that. Maybe it crawled in from the outside? Do these insects hibernate? I’d like to not kill it, but I don’t know if I want it in the house, as it’s a bit big. -Eugene
This is a cockroach; I cannot be certain because of the perspective from which the image was taken, but it may be a German cockroach, an very common and widespread peridomestic pest species. These do not hibernate, but persist wherever they can find warmth and a food supply.  See elsewhere on this site for some control recommendations, and for links to professional pest controllers in your area. Ed Saugstad, retired entomologist; Sinks Grove, WV.
