Running Crab Spider

6215 Any idea what this guy is? He looked mean just hanging out on the fence. 

Number 6215 – This is a running crab spider (family Philodromidae) in the genus Tibellus; see Click here for an example. Spiders in this genus also are known as slender crab spiders; they all are harmless to humans.

Flea beetle – Phyllotreta sp

6214 In the last week, thousands upon thousands of these tiny tiny beetles have appeared on my fence and house siding. They seemed to suddenly appear out of nowhere. They come in 2 colors (solid black and patterned). This is the first year I’ve noticed them, but this is also the first year I’ve had a lawn or fence (sod laid last fall, just bare ground with no plants prior as I live in a new development). Are these just harmless beetles that have all hatched at once and will disperse on their own in the coming weeks or do I have a pest problem on my hands? Thanks so much!

Number 6214 – These are flea beetles, leaf beetles (Coleoptera: Chrysomelidae; tribe Alticini). Some species can be very serious garden pests; the one you imaged looks like a Phyllotreta sp. – Click here for more detailed information,

Hacklemesh/Lace weaver spider

6213 Found this guy in my kitchen and handily escorted him outside to play, but am very curious as to what kind of spider it might be and should I have granted him leniency?

Number 6213 – This is a hacklemesh/lace weaver spider (family Amaurobiidae); like the vast majority of spiders, it has venom glands and thus technically can be considered venomous. However, they are not at all dangerous to humans. This spider appears to be Callobius severusClick here for more information.

Owlet Moth Caterpillar

6212 – Please help identify. From Samarth park, Surat Gujarat India

Number 6212 – This is a caterpillar of a moth in the family Noctuidae (owlet moths). It belongs to a subset of that family that includes many pest species such as cutworms and armyworms, but I cannot provide a more specific i.d. at this time.

Ground Beetle

6211 – Big Black Beetle from outside determined to make it to our door. Found this critter approx 1” long, not including antennae, on an evening of late May, outside on patio and was cooler temps. Top and bottom all black. Wondering what it is. From Saskatoon, Saskatchewan.

Number 6211 – This is a ground beetle (Coleoptera: Carabidae); it looks like Carabus nemoralis, an introduced European species. Ground beetles are for the most part, general predators on other small invertebrates. This species appears to specialize on slugs; Click here for more detailed information.

Spider Beetle

6210 I am not sure what this bug is, my wife has seen the bugs at least 3 times. From Toronto Ontario

Number 6210 – This is a spider beetle (Coleoptera: Anobiidae; subfamily Ptininae) in the genus Mezium. These beetles are cosmopolitan nuisance pests that sometimes can infest dry stored food products, Click here for detailed information and also Click here for more information.

Moth Fly

6209  Hello, I live in Burlington Ontario. We have those flying insects, they look like flies but shorter with more round wings, they fly very quietly so they are not annoying like flies or mosquitoes but they started to get everywhere, we found them inside the coffee machine in couple of cases. Are they harmful? Where did they come from? How to stop them? From Burlinton, Ontario

 Number 6209 – This is a moth fly (Diptera: Psychodidae), Click here for an example. Also known as drain flies or sewer flies, these are nuisance pests that cause no real harm. Their larvae usually are found in small accumulations of very foul water, such as in seldom used floor drains or drip trays under refrigerators. Click here for more detailed information including control suggestions.

Scarab Beetle

6208  Found this guy on my screen door over the last couple nights around 11 pm. From Prince George, British Columbia.

Number 6208 – This is a type of scarab beetle (Coleoptera: Scarabaeidae) that often are called May beetles or June bugs as they usually are most commonly seen in those months. They are attracted to lights at night, but are rather bumbling fliers and thus frequently seen on the ground under outdoor lights. Their larvae (white grubs) feed on roots of grasses and can be serious lawn/turf pests.

Sixspotted Orbweaver

6207 Hi there, I saw this very small spider in a flower. I’ve tried very hard to figure out what type of spider it is and I even looked at your identification photos with no luck. The picture is as zoomed in as my camera could get. As you can see it is bright yellow with bright red legs and red dots. It was in the summer and was found outside. I would love to know what kind of spider it is. Thanks

Number 6207 – This is an orb-weaving spider (family Araneidae); it looks like Araniella displicata, known as the sixspotted orbweaver . Click here for more detailed information.

Orb-Weaving Spider

6206 – Spider Identification

Number 6206 – This is a male orb-weaving spider (family Araneidae); likely in the genus Araneus. All orb-weaving spiders are harmless to humans.

European Hornet

6205 Please help identify, its about 2 inch long

Number 6205 – This is a European hornet (Vespa crabro; Hymenoptera: Vespidae). This introduced species is the only true hornet in North America as well as being the largest member of its family (Vespidae) here. It has been my personal experience that these are less aggressive than our native yellow jackets or bald-faced ‘hornets’, but care should still be taken when near their nest. Click here for more information.


6204 I have a lot of small, brown worms, coming out onto my garage floor, what are they? A friend said they were “Wire Worms”. They come in, curl up and die. How can I kill them before they get in?

Number 6204 – This is a millipede (class Diplopoda). Ones like this are harmless scavengers on decomposing organic matter that may become nuisance pests when they get indoors. They need ample moisture in order to thrive, so simply keeping your dwelling as dry as possible will discourage them.

Stone Centipede

6203 – I’ve increasingly been seeing these I’m assuming “house centipede in my washroom and I have found one in my roof on the roof. I live in the basement and always have the fan running to exhaust the humidity. I found this under a fairly wet mat. After I picked it up I found it and was shocked it survived under it. What is it specifically and how can I get rid of them? This one is the largest I’ve seen this season so far! From Chestermere Alberta.

Number 6203 – This is a stone centipede in the order Lithobiomorpha. These are harmless to humans, and there is no need for control. They actually may be helping out by eating other arthropods in your home. Click here for more information.

Ichneumon Wasp

6202 I was letting the dog in and this thing flew into the house. I grabbed it to put it back outside and the jerk either bit or stung me! Nowhere near as bad as a wasp or bee sting but still a little stabbing pain for 15 min or so. The bug looked to be a little over an inch long from tail to head. From Winnipeg.

Number 6202 – This is an ichneumon wasp (Hymenoptera: Ichneumonidae) in the subfamily Ophioninae. These primarily are parasitic on the larvae/pupae of moths (one species parasitizes larvae of a scarab beetle). Although not venomous, they can give a sharp ‘sting’ with their needle-like ovipositor (personal experience).

Flat bug

6201 found this on a package I had received this afternoon. Bug was fairly flat. Didn’t fly off when I knocked it off. From Concord US.

Number 6201 – This is a flat bug (Hemiptera/Heteroptera: Aradidae); it looks like Aradus quadrilineatus, a species associated with beech, elm, oak, and poplar trees. Very little appears known about its life history, it may feed on fungi associated with the trees where it has been found. 

Ground Beetle

6200 We found him crawling around the base of our garbage bin inside of our apartment. We did have our balcony door open earlier in the day, however I’m just concerned that this may be a cockroach?? From Welland, Ontario.

Number 6200 – This is a ground beetle (Coleoptera: Carabidae); the vast majority of these are general predators on other small invertebrates. They sometimes accidentally get indoors during their searches for prey.

Blister beetle

6199 – Please help identify

Number 6199 – These are a type of blister beetle (Coleoptera: Meloidae) in the genus Meloe commonly known as oil beetles. When handled roughly, they exude am oily fluid from their leg joints that contains a chemical called cantharidin that can cause blisters on tender skin – see American Oil Beetle for more information.

Wolf Spider

6198 This spider was found in Tecumseh Ontario, in grass of my backyard. Its body is a good inch long, black, legs were brown and black, before I killed it. The legs are all shriveled up now and in this picture, one leg is broken off. I believe it to be a tarantula. If you can zoom in, you can see eyes and fuzz on body and legs. When it was alive and crawling, it was good 2 inches in diameter. It also had an opening at back of body.

Number 6198 – This is a wolf spider (family Lycosidae); it looks like Tigrosa (formerly Hogna) helluoClick here for an image. These spiders are active hunters that run down and capture their prey, they do not spin capture webs. These are excellent volunteer pest controllers that are not at all dangerous to humans.

Conifer Seed Bug

6197  Found this beetle inside my home and don’t know what it is. Can you please help identify and how did it get inside!

Number 6197 – This is not a beetle; it is a western conifer seed bug, Leptoglossus occidentalis (Hemiptera/Heteroptera: Coreidae). These often enter buildings in search of shelter, but do no harm there. Click here for more detailed information.

German cockroach

6196 Please identify this bug found around and in my office it’s black with red on its back.

Number 6196 – This is a German cockroach, Blattella germanica (Blattodea: Ectobiidae), a cosmopolitan pest species that can be difficult to bring under complete control. Click here for additional information and control recommendations.

Wolf Spider

6195 What kind of spider is this?

Number 6195 – This is a wolf spider (family Lycosidae). These are active hunters that have good eyesight; they do not spin a capture web. They are not aggressive towards humans, but large specimens can deliver a painful bite if handled carelessly.

Terrestrial Crustacean

6194 Please help identify

Number 6194 – This is a terrestrial crustacean in the order Isopoda; they go by a variety of common names including sow bugs, pill bugs, slaters, roly polys, woodlice, etc. They primarily are harmless scavengers on decomposing organic matter, but a few species occasionally can damage very tender vegetation.

leaf beetle

6193 We have had a number of these in our basement lately (April 2018, North Vancouver, B.C.) primarily, but not always, in the bathroom. They are about 4-5 mm in length with black backs/wings with a distinct brown patch towards the head. I’m not sure if they can fly… they sometimes seem to jump. Thank you for any assistance you can provide!

Number 6193 – This looks like a leaf beetle (Coleoptera: Chrysomelidae); if they can jump, they may be flea beetles (tribe Alticini in said family). to the best of my knowledge, none of these are household pests, yours likely are simply accidental intruders.

Ichneumon Wasp

6192 I’m from Prince George, BC. I found this bug in my basement April 2018. We have had a bizarre winter (cold, warm, lots of snow, melting, freezing etc), but now it is quite mild and finally looking like spring.

The bug looks like an ant but has a really long “tail” and wings. It’s between 5-10 m long from antennae to end of the tail. Does anyone know what this would be? I’ve lived in Prince George my whole life and I have never seen a bug like this before. The bug in the picture was found dead (hard to say if my cat got to it). Any advice is greatly appreciated. I can tell you that the bug is dominantly black and the legs may be a brownish colour.

Number 6192 – This is an ichneumon wasp (Hymenopter: Ichneumonidae); they all are parasitic on other arthropods, primarily other insects, and are harmless to humans (and cats).


6191 We’re in Montreal’s West Island area. We have these bugs in the house and they’re usually found in pasta but also marshmallow etc. in the pantry.
I haven’t seen them before and am wondering whether they came in some flour or something.

Number 6191 – This is a weevil (Coleoptera: Curculionidae), based on your narrative it most likely is one of the grain /granary weevils in the genus Sitophilus. These often infest stored grains such as wheat, rice, corn (maize), etc. as well as dry stored food products made from grains (such as pasta). See elsewhere on this site for additional information including control suggestions. Click here

Brown Marmorated Stink Bug

6190 What is it??

Number 6190 – This is a brown marmorated stink bug, Halyomorpha halys (Hemiptera/Heteroptera: Pentatomidae), an introduced species that has become a pest in much of North America. Click here for more detailed information.

Nymph of an assassin bug

6189 What is this bug? At first I thought it was a Kissing Bug or Boll Weevil but upon comparing stock photos online, I don’t think so.

Number 6189 – This is a nymph of Reduvius personatus, an assassin bug (Hemiptera/Heteroptera: Reduviidae) known as a masked hunter. This is an introduced species likely of European origin that is frequently found indoors where it feeds on the insects and other arthropods it finds there. It is reported to have a very painful (but not dangerous) bite; Click here for more detailed information.

Carpenter Ants or not?

6188  Can you please identify these for me? We want to make sure that they are not carpenter ants.

Number 6188 – This does have the appearance of a carpenter ant (Camponotus sp.), but a clear view from the side would confirm this. The top of the thorax of a carpenter ant is smoothly rounded, whereas that of most other ants is not – Click here for an image.

Larder Beetle

6187 – Just Wondering what this is.

Number 6187 – This is a larder beetle, Dermestes lardarius (Coleoptera: Dermestidae), a cosmopolitan pantry pest. Click here for more detailed information.

Elm seed bug

6186 I am located in Penticton BC these are in my garage/gym, they are mostly dead and i have to vacuum them daily in the hundreds. Thanks

Number 6186 – Like nos. 6177 and 6182, this appears to be an elm seed bug, Arocatus melanocephalus (Hemiptera/Heteroptera: Lygaeidae).  These are nuisance pests that do no real harm; Click here for more detailed information. 

Bug OR Bettle

6185 I got this bug or beetle in my house today and couldn’t identify it.
Pls let me know what is it. Where did it grow or come from and how to control this. Is it harmful. Thank you

Number 6185 – This appears to be a nymph of a soft tick (family Argasidae); it
likely dropped off whatever host it had been feeding on, and is looking for its next
meal. Some of these ticks can be disease vectors – for more information Click here
 And also for some tick control suggestions,  Click here 

Assassin Bug

6184: This bug bite me and it was worse then a new sting it’s swelled up and now it’s dark red circle where it bite me and itchy like crazy still not healed it been 5 days now I have looked every where to what kind of big this is and asked no one seen this kind before please help

Number 6184 – This looks like Reduvius personatus, an assassin bug (Hemiptera/Heteroptera: Reduviidae) known as a masked hunter. This is an introduced species likely of European origin that is frequently found indoors where it feeds on the insects and other arthropods it finds there. Its bite indeed has been reported as very painful, but not dangerous; Click Here for more detailed information.

Possibly a baby spider

6183 From Toronto: Found a huge black spider in the bathroom, could fit over a toonie, not hairy legs but thought it could be a black widow, sorry no pix, freaked out and just killed it. also next to it a speck of dust that moved, so a baby.. ID?

Number 6183 – I believe that it is extremely unlikely that your spider would
have been a black widow; it also is extremely unlikely that the moving
‘speck of dust’ would have been any baby spider.

elm seed bug

elm seed bug

6182  Have found several in the second floor of house over a few weeks – insect smells with sharp odour when crushed – what are they? Regards,  Larry D.

Like no. 6177, this appears to be an elm seed bug, Arocatus melanocephalus (Hemiptera/Heteroptera: Lygaeidae). See for more detailed information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

Stink Bug

Stink Bug

6181  Hello,  Trying to figure out what came in on my Christmas tree. We are in Calgary, AB area and the store tells me the tree came from out East- likely Quebec or NB. The tree was outside for several days, but it has been a very mild winter ( typically above freezing days).  Cheers,  Tanya

This is a stink bug (Hemiptera/Heteroptera: Pentatomidae) in the genus Chlorochroa, possibly C. ligata, a species widespread in Canada; see for some images. This species appears to feed primarily on developing seeds, especially those of plants in the legume family. It does not appear to be a serious pest species in Canada, but has been reported to damage cotton bolls in the southern United States where it is known as the conchuela stink bug. Ed Saugstad, retired entomologist; Sinks Grove, WV.


silverfish or firebrat

silverfish or firebrat

6180   Hello -Shawn here in Prince George B.C.and we are experiencing a mild winter so far this December 2017. We found this unusual critter walking in a shower that does not see regular use & can not seem to identify it. It was @ 8 – 10 mm long and seemed sensitive to light changes/movements. We are just wondering if it crawled in or if it may be an indicator of other issues (mold / mildew or other moisture caused issues)

This is a bristletail (Zygentoma: Lepismatidae), I cannot tell from this image whether it more likely is a silverfish or firebrat. Both basically are nuisance pests that usually cause no real harm. See for more detailed information and control recommendations. Ed Saugstad, retired entomologist; Sinks Grove, WV.

case-bearing clothes moth

case-bearing clothes moth

6179  Found this in our home in Chilliwack, BC, late November 2017.  It acts like a tube worm, it has been impossible to photograph when the head is out as it seems to be incredibly sensitive to noise and light.  Mark

This looks like a case-bearing clothes moth, Tinea pellionella (Lepidoptera: Tineidae). See elsewhere on this site for more detailed information and control recommendations. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Fungus gnat

Fungus gnat

6178  Hi there, I live in Halifax, Nova Scotia and have found a whole lot of these flies in pretty much all of my windows this November- upstairs and in the basement. There was some condensation on some of the windows. They are usually dead or not very active, but have reappeared after spraying with raid. Should I be concerned. How do I get rid of them?   Thanks,   Rachel

This looks like a fungus gnat, possibly in the family Mycetophilidae. These basically are nuisance pests; the adult flies cause no harm, but the larvae of some species can damage roots and lower stems of tender plants, especially in greenhouses or in indoor pots. If you have indoor potted plants, check soil moisture levels – the soil should be allowed to dry out as much as practical between waterings. Ed Saugstad, retired entomologist; Sinks Grove, WV.


elm seed bug

elm seed bug

6177  Hello,. This bug is smaller than most that we’ve had, at about 3mm long.  They fly, and when threatened, they just fall and start to fly.  We live in Kelowna BC and we started getting these at the end of summer, and it’s now Nov. 30. They are attracted to our Lipstick plant that blooms small red flowers and have sap that the bugs are, I think, feeding off of.  The leaves were covered in them!  Last night I rinsed the plant off and many baby sized bugs came off, like this one.  Sadly, we can’t seem to get them all so the plant is outside now.  Some of the bugs have been hiding in our Jade plant but not nearly as many, so we’re hoping we got rid of their food source, but we found two more on the ceiling, this was one of them. If you can help that would be fantastic!   Thank you kindly,  April

This is an elm seed bug, Arocatus melanocephalus (Hemiptera/Heteroptera: Lygaeidae), an introduced species that has become a nuisance pest in many areas. See for more detailed information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.




Pack Rat

Pack Rat

What is this critter living in my garage? How do I remove it? It is November in Grande Prairie Alberta Canada.

This is a pack rat, sometimes called a wood rat or bushy tailed rat.  They can be eliminated using rat traps baited with nuts or peanut butter.





6175  I cannot tell if the rat on the top of the pictures is a Norway rat or a black rat.  It is much larger than the rest of what appear to be black rats.  These rats were trapped on Tinian Island, Commonwealth of the Northern Mariana Islands. They were trapped with Victor rat traps, baited with peanut butter and oats.  Any help greatly appreciated.  Best regards,  Brian, Research Associate, Center for Environmental Management of Military Lands,   Colorado State University.

Only three species of rat, all introduced, have been reported from Tinian. The commonest species is the roof rat, Rattus rattus, likely was brought in by Europeans. The Polynesian rat, R. exulans, likely accompanied early Polynesian settlers, and does not appear to have been reported from Tinian since 1945. The Norway rat, R. norvegicus, was reported in 1913, but that identification now appears doubtful. For details, see “The mammals of Tinian, Mariana Islands” ( The appearance of hair on the tail of the larger rat likely is an artifact of the tail having been crushed to some extent. I believe that it most likely is an adult male roof rat. Ed Saugstad, retired entomologist; Sinks Grove, WV.


Bed bug

Bed bug

6174   Hi there. I found this bug in a bedroom on the floor last evening in Scarborough ON. Could you please identify if possible. Thank you! Cecilia

The photo is a little out of focus but it is obviously a bed bug.   
See our suggestions to control your problem. .


harmless accidental intruder

harmless accidental intruder

6173  Hello,  I live in Burlington, Ontario and I found a very small worm/caterpillar on the wall. Can you ID it for me? It moved very slowly in a wave-like manner. Pics are attached. Any help would be greatly appreciated. Thanks    RM.

This is a caterpillar, but I cannot make a more specific determination from this image. At least it does not appear to be any of the common household pest species and thus likely to be a harmless accidental intruder. Ed Saugstad, retired entomologist; Sinks Grove, WV.


Plant seeds

Plant seeds

6172  Attached is a photo of possible bug eggs that were found beneath a baseboard heater in Ottawa, ON. The bottom of the heater is very dusty but these “eggs” were not which suggests that they are new, although this is unknown. It is currently November and there is snow on the ground. These “eggs” were found indoors. They are about the size and shape of popcorn kernels. It is also unknown what the two larger objects are (the long one on the carpet on the bottom left and the one on the baseboard heater on the top right). Please let me know if any of these look familiar. Thanks. Erin

These objects look to me to be more likely plant than insect-related; certainly do not look like typical insect eggs. Do you by any chance have mice on your premises? If so, they might have brought these in. Ed Saugstad, retired entomologist; Sinks Grove, WV.


big-eyed bug, Hemiptera

big-eyed bug, Hemiptera

myself:   Shriram
crop: cotton
month: November
weather: low temp 20 degree c.

This is a big-eyed bug, Hemiptera/Heteroptera: Geocoridae); they are general predators on other small arthropods and this usually considered as beneficial. Nice photo!  Ed Saugstad, retired entomologist; Sinks Grove, WV.

Wood boring beetle larva

Wood boring beetle larva

6170  Hello & please help Identify the attached larva;  The hole in the oak floor is where the larva was found. White powder sawdust was removed with an air blast and the larva was coaxed out by injecting wasp foam spray into the bore hole about 3-1/4” long. The home is located between Brantford and Paris Ontario.  Thanks;   Gord


This looks more like a larva of a long-horned wood-boring beetle (Coleoptera: Cerambycidae). Larvae of flat-headed wood-boring beetles (Coleoptera: Buprestidae) can be quite similar in appearance except for having their thoracic segments (immediately behind the head) somewhat to greatly flattened (see for an example). This results in their exit holes being noticeably oval in cross section whereas those of round-headed borers are circular or nearly so. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Yellow mealworm beetle pupa

Yellow mealworm beetle pupa

6169   This 6 legged insect may have entered my house on a jacket  that was left outside overnight.  Two days ago it seemed lifeless after my cat discovered it, soft, moist and pale like shrimp but now it’s segments are dry and more solid… then it wiggled when handled for the photo so perhaps I’ll return it to the thickets once this rain lets up.  I hope you might be able to identify it as friendly and native to my area?  Mild in October, near a mix of wooded swamp and wild fields in Trenton, Ontario.

This is a pupa of a beetle; likely that of a yellow mealworm (Tenebrio molitor; Coleoptera: Tenebrionidae); see for an image. These beetles are cosmopolitan in distribution, and sometimes can be pests in stored grains, especially those that have been damaged by excess moisture. See for detailed information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.


western conifer seed bug

western conifer seed bug

6168     Found inside and out, mainly spring and fall.  They all look to be of same size and colouring.  Property near tidal water.  Thanks,  Mark.

This is a western conifer seed bug, Leptoglossus occidentalis (Hemiptera/Heteroptera: Coreidae). These often enter buildings in search of shelter, but do no harm there. See for detailed information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

ant-like flower beetle

ant-like flower beetle

6167  This specimen was caught in a bug trap (baited with black and varied carpet beetle pheromone and a food pellet), placed in a carpeted lunchroom near a wall and a radiator. We collected this specimen on October 23, 2017 (specimen was likely caught in trap within the last week). Our geographical location is Burlington Ontario.  Thanks,  Corey.  Botany Intern, Royal Botanical Gardens

This looks like an ant-like flower beetle (Coleoptera: Anthicidae); see for an example. Some of these will infest stored grains and dried fruit; see for detailed information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

female orb-weaving spider

female orb-weaving spider

6166 Hello I would greatly appreciate it if you could help me identify this spider thank you.  Nicola

This is a very well-fed (and likely gravid) female orb-weaving spider in the genus Araneus, likely A. diadematus, a very common and widespread species in the northern hemisphere. In North America, it usually is called a cross spider whereas in Europe, it usually is called the European garden spider. See for more detailed information  Ed Saugstad, retired entomologist; Sinks Grove, WV.
