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.

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.

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.

Millipede

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 Isoptera; 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).

Weevil

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 https://tinyurl.com/y77dynqq 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 https://tinyurl.com/ydcsywmr 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.
