redlined carrion beetle

carrion/burying beetle

5807  HI my name is Kevin. I’m from Sundre, Alberta, Canada. It’s the beginning of fall.  I have found these beetles in my house before and upon hours of looking online I can’t seem to find a match for them. Ive found some close but not the same. This one is approximately 2-2.5cm long. And they smell absolutely vile when you kill them.

This is Necrodes surinamensis, a carrion/burying beetle (Coleoptera/Silphidae) known as the redlined carrion beetle. Beetles in this family are nature’s recyclers, disposing of the carcasses of small birds and mammals as they feed their young; see for more details. In the future, please release outdoors any of these that should find their way inside, so that they may carry out their duties.

western conifer seed bug

western conifer seed bug

5806    Can you please let me know what kind of bugs these are? My husband mentioned how they looked like Chagas (the kissing bugs) and I’ve been worried ever since. We live in Bc Canada and they have been all over our house for the past month. Thanks

This is a harmless nuisance pest; it’s a leaf-footed bug (Hemiptera/Heteroptera: Coreidae); likely a western conifer seed bug, Leptoglossus occidentalis. These commonly enter buildings in search of shelter, but do no harm there; see for more detailed information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.


predaceous diving beetle

predaceous diving beetle

5805   Hi. My name is Tim, and I am located in Hanwell, New Brunswick. I found this dried out husk in my patio door track. I believe it may be a dried out, deflated June Bug, but I wanted to make sure it wasn’t something nasty that got into my house. It appears to be a very dark green with a split down it’s back. It is a large specimen.  This is a very useful site. I have identified many strange looking bugs here. A great resource to have.  – Tim –

This is a predaceous diving beetle (Coleoptera: Dytiscidae), likely either Cybister fimbriolatus or Dytiscus verticalis (the distinguishing characters cannot be seen in this image. These beetles and their larvae (water tigers) are general predator on other small aquatic life forms, usually other insects, but occasionally small minnows and tadpoles. The adult beetles are strong fliers, and often can be found quite some distance from the nearest water. Ed Saugstad, retired entomologist; Sinks Grove, WV.

fungus feeder or scavenger

fungus feeder or scavenger

5804    I live in Minnesota and have never seen this tiny super bright red beetle type bug that borrows little holes all over the place. I pulled this long out of my old 1800’s Catholic Church that rest on my farm. Weather right now is 75 and hardly any humidity. It Sept.19th 2016. And I wouldn’t have ever seen them but I wash old logs and restore them into useful objects. And while soaking log to the point of satcheration it forced them up out of the holes. Please tell me what they are and how to get rid of these before I lose a very old sacred place. My great great great great grandfather built. Now converted into log storage. Thank you!

This does not resemble any of the wood-boring/damaging beetles that I am familiar with; I rather suspect that it might be either a fungus feeder or scavenger. Just because an insect is found in a hole does not mean that it made it. Ed Saugstad, retired entomologist; Sinks Grove, WV.




5803   Hi there, I found this very tiny insect in my bathroom. It has an oval shape and yellow color, 6 legs and 2 antennas. The macro zoom is 19x. Could I please know the name of this insect?   Thank you in advance,   – Gregory

This is not an insect, but a mite. What appear to be antennae actually are its first pair of legs. There are several other arthropods lacking antennae that use one pair of their legs (usually the first pair) as if they were antennae. I cannot tell exactly what kind of mite this is, but it does not appear to be a biting kind like bird or rodent mites. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Cave orb weaver spider

Cave orb weaver spider

5802  This is a spider that had MANY buddies, they were in the crawlspace under a house our employees were working in Muskoka Lakes, Ontario.  Him and his friends scared the guys, they are convinced he is toxic, I believe he is not.  Would you like to settle our argument. Jennifer. 

This spider, Meta ovalis, is harmless to humans; it is in the family Tetragnathidae (long-jawed orb weavers) and is commonly known as the cave orb weaver, as it often is found in dark, undisturbed places like caves (and crawl spaces); see for details. I have seen quite a few of these in West Virginia caves. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Box Elder Bugs

Box Elder bug swarm

5801  My name is Cynthia Reason and I’m a reporter with Metroland Media Toronto.  I was wondering if you can tell me if the insects in the attached photo are Box Elders Bugs or not?  We’ve had a couple of concerned residents contact us about a fairly large swarm of them in York, and we were hoping to shed some light.  Also, would you be willing to comment for the story, addressing the fact that they are merely a nuisance pest, but not necessarily harmful? Thanks for your time! Cynthia. 

Yes the photo you sent is a typical swarm of box elder bugs.  Apparently this is common in Ontario at this time of year.  They are seldom seen in B.C. so I personally never had to deal with them when I was in the pest control business for 20+ years.   They are harmless to humans and any damage to vegetation is minimal.  If they die in wall cavities of a home, the carcasses can be a food source that will attract other pests such as carpet beetles.  Please see  for more information.  If they become too much of a nuisance, a simple, inexpensive and safe control solution is to spray the clusters with soapy water.  (Safer Soap is available at most garden shops)  There are more suggestions on the web page.

Dermestid Beetle

Dermestid Beetle

5800  Hello, found this little guy on my pillow this morning in my apartment. About 4mm long. I believe he has wings but has not flown. I don’t have any bites on me (I’ve had bedbug bites in the past while travelling). No other signs of bugs or feces. Please keep me know what you think.  Thanks, Jill

This is a beetle in the family Dermestidae (hide/skin/carpet/larder beetles, etc.); it looks like an Attagenus sp. (black carpet beetles and allies). See elsewhere on this site for control/management suggestions.  Ed Saugstad, retired entomologist; Sinks Grove, WV.


Foreign grain beetle

Foreign grain beetle

5799  Hi, I’m from waterloo Ontario. I am finding these tiny beetle bugs constantly in my home. I have no idea what they are or if it’s a real issue. I’ve attached a few pictures. Thank you Samantha

This appears to be Ahasverus advena (Coleoptera: Silvanidae), a nuisance pest known as the foreign grain beetle or new house beetle – see for images and more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.



5798  Hello I am from winnipeg Manitoba, it is September 15th and in the 20s for out door temperature. I found this bug climbing down my wall in my house, I am going through bed bug treatments and was last sprayed September 13th. I am hoping that what ever this bug is, that it is the only one in my unit. I have attached a photo of his back and underside, please help me identify this gross bug.   When it is on its back it flips it’s self over using its butt, a cone shipped thing that comes out from its underwhelming then retracts back when it is on its feet. Eww

This is a firefly (Coleoptera: Lampyridae); likely in the genus Ellychnia, see for an example. Unlike most other fireflies, ones in this genus tend to be active during the daytime rather than in the evening. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Boxelder bugs

Boxelder bugs

5797    Hello.   I am in Kingston, ON and curious to know what this specimen might be.  I found many of them sunning themselves on the stucco of a foundation.   Thank you for this service,   Matthew.

These are boxelder bugs (Hemiptera/Heteroptera: Rhopalidae; Boisea sp.); likely the eastern boxelder bug, B. trivittata. These basically are nuisance pests that do little if any real harm – see for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.


female orb weaving spider

female orb weaving spider

5796  Can you please tell me what kind of spider this is. Found on a cement pad in Thunder Bay, Sept 13/2016 Sunny weather, Helen

This is a female orb weaving spider in the genus Araneus that has deposited her eggs and is approaching the end of her natural life. Both A. marmoreus and A. trifolium can have a similar appearance under this condition; I am inclined to believe that this more likely is A. trifolium. See for another example. Ed Saugstad, retired entomologist; Sinks Grove, WV.



5795   Found in our daughter’s bed after she woke up with bites!  Measures about 1-2mm – very small!  Thank you!  Susi.  Calgary.

This a flea that will feed on any warm blooded creature, especially humans.  To eliminate them in your home 1) Take your pets to a vet for treatment, 2) Vacuum, Vacuum, vacuum. 3) Have a pest professional treat your home with residual products that will kill the adults and insect growth regulators to eliminate the eggs and larva.  (IGR).

Sexton beetle

burying/sexton beetle Beetle with hitch-hikers

5794  Hi I’m wondering what kind of bug this is. It’s a beetle type bug with little red spiders/ticks all over it. It flew in my car window as I was driving. My name is Brad and I live in Bancroft Ontario Canada.

This is a burying/sexton beetle (Coleoptera: Silphidae) in the genus Nicrophorus. The little red critters are mites that are using the beetle as transportation (a phenomenon known as phoresy) to get to their next meal source – see for an image. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Well fed bed bug

Well fed Toronto bed bug

5793  Last night I sent a picture of a bug I found in my bed. It was taken with my cell. I found a live version of this bug this morning on my carpet and have taken a better picture with my camera (I hope). I really hoping it isn’t a bedbug. Once again, I live in Toronto and this bug is easily squished and has a lot of blood in it. Thanks for your help.

This, unfortunately is a bed bug that has had a good blood meal.   The best control solution is to call an experienced pest professional.  In the mean time do not spray pesticides that could scatter them making it more difficult to find others.  See our web page for helpful information:

orb weaving spider

Common orb weaving spider

5792   My nabour has this one in her garden. She is wanting to know the name of it pls.

This is Argiope aurantia, an extremely common, widespread and harmless (to humans) orb weaving spider. See for much more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.



Reproductive winged ant

Reproductive winged ant

5790  Hi,   My name is Leslie and we live in Calgary.  We noticed hundreds of these flying insects (both large as in the picture and many very tiny ones as well) around a large window on our stair landing and then found hundreds more along the base of one wall in an unfinished part of our basement.  We sprayed the basement and it immediately killed them and then we vacuumed up the rest on the landing.  We haven’t seen a single one in the last  week so it seems we’ve eradicated them.  I would like to know if these little guys do any damage and if it’s likely they will come back.  Many thanks for your help!

This is a winged ant, likely a female ‘queen.’ Unfortunately, I cannot tell what kind it is from this image; the only ones to be concerned about from a damage standpoint are carpenter ants in the genus Camponotus. See elsewhere on this site for detailed information on these pests. Ed Saugstad, retired entomologist; Sinks Grove, WV.

cockroach nymphs

cockroach nymphs

5789  We are trying to identify the attached insects.  My location is Albuquerque, NM.  They are very small, between 4-5 mm (~3/16ths of an inch), end to end, not including antennae.  We are concerned these could be immature roaches, but we have lived here ten years and have never had them.  We have not seen any adult insects.  We are in a condo on the second floor, with one unit below part of our own.  The insects are showing up on the kitchen floor, either dead or dying.  We only spray outdoors, so we aren’t sure if these are coming in from the outside (deck, about 15 feet from the kitchen), or if they hatched inside.  If they hatched indoors, then we can’t explain what is killing them.  Also, we would expect to see a more signs, and greater numbers, not just two or three each day.  We have seen approximately eight total, but can’t identify where they are coming from. Thank you.  Any help in identifying the insects and recommendations to control is greatly appreciated. Kurt

These are very young cockroach nymphs, but I am uncertain as to exactly which species they might be. You might check with the owners/occupants of adjoining units to see if any had recently initiated any pest control measures. In the meantime, you might set out some ‘roach motels’ to see if you can get a better idea as to the extent of your infestation. Cockroaches essentially are nocturnal, so you might see only a few during the daytime even if a relatively heavy infestation is present. Ed Saugstad, retired entomologist; Sinks Grove, WV.

white-margined burrower bug nymph

white-margined burrower bug nymph

5788   Hi, this is Lili from Moncton New Brunswick. Found these bugs around outdoor plants in early September.  They are very small, with black head, red body with stripes. And they appear in groups. There are some little red things around them, not sure whether those are eggs or babies. Please help, thanks!  Lili

This appears to be a nymph of a white-margined burrower bug, Sehirus cinctus (Hemiptera/Heteroptera: Cydnidae). These are not pests that need any control; see for images and detailed information on its life history. Ed Saugstad, retired entomologist; Sinks Grove, WV.


Tussock moth caterpillar

Tussock moth caterpillar

5787   Hi.   This was found in Prince Edward Island (Sept 2016).  It is about 2” long +- and found on the grass by our propane tank. The 4 things on its back seemed to be soft and looked like the ends of paint brushes.  Any Idea of what type of caterpillar this is?  Thanks,  Derek

This is a caterpillar of a tussock moth (Lepidoptera: Erebidae; subfamily Lymantriinae) in the genus Orgyia; likely Orgyia leucostigma, the white-marked tussock moth. See for detailed information on its life history. Ed Saugstad, retired entomologist; Sinks Grove, WV.

crane fly

Crane fly

5786   My name is Nolen.  I live in Delta, BC and it’s late summer. What is this thing I killed?  Thanks,  Nolen

This is a crane fly.   The adults are a nuisance but considered harmless.  The species common in the pacific northwest are a serious problem because the larvae,  also known as leather jackets, feed on the roots of plants, mainly turf grass. Sometimes crane fly populations get high enough to cause damage to lawns.

Reproductive termites

5785   From Al, BC coast, Canada.  Any idea what these are? quite a few around today in our house (September 3rd) never seen them before.  Many thanks

This is a pair (male pursuing female) of reproductive termites. They often form pairs like this after emerging from their colony and shedding their wings. After mating, the female will attempt to found a new colony. As most people are not keen on hosting these critters, locating a certified termite control service might be a good idea – see elsewhere on this site for a starting point. Ed Saugstad, retired entomologist; Sinks Grove, WV.
Western subterranean termites have acute survival instincts. If they are shaken up or disturbed, the termites often will abandon the associated area and move on to secretly cause damage in other areas in the building.  Get help from an experienced pest control professional.

male beetle in the family Phengodidae

beetle in the family Phengodidae: glow-worms, railroad beetles

5784  Hello i live in mn.. I know it’s not Canada but I hope close enough for you help. I’ve looked everywhere for this bug in the net and can’t find it.. please help identify.

Nice find! This appears to be a male beetle in the family Phengodidae (glow-worms, railroad beetles). See for detailed information on these fascinating insects. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Orb weaving spider

Orb weaving spider

5783   Hi there, Just wondering if you can id this spider for me. I took this photo this afternoon in a mosquito net under an apple tree nearby. I’m in Grantville, Cape Breton. It appears to have a small web in the net’s peak. It’s about 3 cm long tail to tip.  Thanks.  Adam

This is a male orb weaving spider in the genus Araneus; likely A. marmoreus, an extremely variable species. See for another example. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Sphinx Moth caterpillar

Sphinx Moth caterpillar

5782    This  Caterpillar was in Regina SASK Canada in AUG.  2016     Thanks  Conrad

This is a fully grown caterpillar of a sphinx moth (Lepidoptera; Sphingidae); likely an Achemon sphinx, Eumorpha achemon. See for images and details on its life history. Ed Saugstad, retired entomologist; Sinks Grove, WV.

broad-nose/short-snouted weevil

broad-nose/short-snouted weevil

5781  This bug was found inside our hotel room in Vernon BC. It is the third we have found in the bedroom.

Like Nos. 5779 and 5774, this is yet another broad-nose/short-snouted weevil (Coleoptera: Curculionidae; subfamily Entiminae). These weevils often enter buildings in search of shelter, but do no harm there. Ed Saugstad, retired entomologist; Sinks Grove, WV.


long tail black bug

Pelecinus polyturator

5780   I have been seeing this bug recently here in Saint John NB in my back yard. The bug is smaller then the photo makes it out to be. The body of the bug is about a cm and the tail would be about 4-5 inches. It also flies. Please let me know if you know what this bug is. Thank you!

This is Pelecinus polyturator  (Hymenoptera: Pelecinidae), it is parasitic on the larvae (grubs) of beetles in the family Scarabaeidae. See for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

broad-nose/short-snouted weevil

broad-nose/short-snouted weevil

5779   Whitehorse, Yukon Territory. We are finding numerous bugs in our house (15-20 a day) … we would like to know if this is a pest and what steps we should take. Please see attached photo. additional info: very slow moving. 7-8mm long… , stop moving for a long time when we disturb them, VERY hard shell, everywhere in the house on walls, ceilings, floors … not sure if they can fly.   thank you very much, Seb. 

Like no. 5774, This is another broad-nose/short-snouted weevil (Coleoptera: Curculionidae; subfamily Entiminae). These weevils often enter buildings in search of shelter, but do no harm there.  Ed Saugstad, retired entomologist; Sinks Grove, WV.


Cat-face orb weaver spider

Cat-face orb weaver

5778   It’s almost 2 inches big. It’s living between the windows (outside and inside) of townhouse in Edmonton. Photo taken mid August of this year. Please, please can you respond. Need to know if something to worry about, as there is a 1 year old baby as well 2 dogs. Thank you.  Dave H.

Nothing to worry about here – it’s a harmless orb weaver in the genus Araneus, possibly Araneus gemmoides, known as the cat-face orb weaver; see for an image. All orb weavers are harmless to humans. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Funnel weaver lair

Funnel Weaver spider lair

5777  Walking in the forest here in French River Ontario,  I came across a bunch of weird looking webs that I had never seen before.  I didn’t see any spider although i did look as close as I dared to.  lol  I have attached a few pictures of the tree with the webs.  I would greatly appreciate if you could identify these for me.  Thanks so much for your time!   Joanne. 

This appears to be the work of a spider in the family Agelenidae. Often called funnel weavers, these spiders lay in wait within their lair until a potential meal wanders onto the web, whereupon the spider rushes out to deal with it. See for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.


Mormon cricket

5776 About 2.5 inches long, on a path in the community forest. What is this thing?

This is a shield-backed katydid, such as a Mormon cricket, Anabrus simplex (Orthoptera: Tettigoniidae); see for an image. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Wood Rat

Wasp or fly larvae

5775  These larval sacks were protected in some fine insulating substance just like wool. Found them in a junction box on a wall outside.  (It even smelled like lambs wool.)  There were about ten of these brown, slightly crispy-shelled sacks.  Only one sack contained a set of 30 or so active larvae, the rest were nearly all milky, yellowish/white liquid. We’re in the Portland, Oregon, U.S. area. Really curious and unusual.  Can anyone help? Barrett and Susan.

This is another head-scratcher; I am unable to determine to my satisfaction whether these are wasp or fly larvae. If at all possible, can the contributor provide any image(s) of the sack-like structures before they were cut open? Ed Saugstad, retired entomologist; Sinks Grove, WV.
