Number 7463.      This is a nymph of a smokybrown cockroach, Periplaneta fuliginosa (Blattodea: Blattidae) . See Smokybrown cockroach information and Smokybrown cockroach more information .


Grain beetles

7462.         We live in Montreal and these are in our pantry and randomly throughout our apartment. Montreal, QC. Canada


Number 7462.     The image is too small for me to be certain, but it might be one of the grain beetles (Coleoptera: Silvanidae) in the genus Oryzaephilus; these are quite common pantry pests. See Grain beetles more information .


Winged ant

7461.        There is a swarm of these bugs dropping onto my back deck, car, roof just everywhere they land. The swarm is flying above some trees in my backyard. I am unable to identify them myself, hoping you guys can! Thanks 🙂 Port Hawkesbury, Nova Scotia. Canada


Number 7461.    This a winged ant, but I cannot tell which species it might be. Swarming of winged ants is just a part of their mating ritual – see Winged ant details .


Broad-nosed/short-snouted weevil

7460.         Hi, What is this bug? We found this at my son’s cloth. So scared. Vancouver, BC. Canada


Number 7460.      This is a broad-nosed/short-snouted weevil (Coleoptera: Curculionidae; subfamily Entiminae). These weevils often enter buildings in search of shelter, but do no harm there.


Rove beetle

7459.        We are on Vancouver Island in a rural area. We suddenly have an influx of small insects in the house. They are quite slow moving, don’t fly, are about 5-6mm long, and seem to be all over the floors. I have never seen them before although we have lived here for 12 years. It has rained recently for the first time in quite a while, but that is the only change in weather. Any thoughts as to what these might be would be greatly appreciated. Thank you. Ladysmith, B.C. Canada


Number 7459.        This is a rove beetle (Coleoptera: Staphylinidae). The vast majority of these beetles are general predators on other small invertebrates, mostly other insects. Rove beetle detailed information .

7457.         Multiple inside the house. West St Paul, Manitoba. Canada


Number 7457.       This is a broad-nosed/short-snouted weevil (Coleoptera: Curculionidae; subfamily Entiminae). They often enter buildings in search of shelter, but do no harm there. broad-nosed/short-snouted weevil image .


Cobweb/comb-footed spider

7456.        Found in small tangled web behind door, near floor. Ottawa, Ontario. Canada


Number 7456.     This is Steatoda triangulosa, a cobweb/comb-footed spider (family Theridiidae) known as the triangulate cobweb spider. Although belonging to the same family as the widow spiders, it is harmless to humans. See Cobweb/comb-footed spider detailed information .



7455.           We found them in the kitchen floor. They are active only at night and are very fast! LaSalle, QC. Canada


Number 7455.    This is a firebrat, Thermobia domestica (Zygentoma: Lepismatidae). They and their close cousins, silverfish (Lepisma saccharina), are scavengers that will feed on just about any organic material, Usually considered nuisance pests, large populations, if left undisturbed, can damage items such as fabrics, wallpaper, books, and other paper. See Firebrat detailed information , including control suggestions.


Cicada nymph

7454.          What kind of insect is this and does it bite? Scarborough, ON. Canada


Number 7454.      This appears to be the empty ‘shell’ (exoskeleton) of a cicada nymph (Hemiptera/Auchenorrhyncha: Cicadidae). When cicada nymphs have completed their development under ground, they tunnel up to the surface and seek out some vertical surface to climb up on, where they will then shed their exoskeleton and rest a while before taking wing as adults. They do not bite.


Ground spider

7453.            Found on deck at back of house. Ottawa, ON. Canada


Number 7453.       This is a ground spider (family Gnaphosidae) in the genus Sergiolus, most likely S. montanus – see Ground spider image . They are not dangerous to humans.


Great golden digger wasp

7452.         I have more pictures but they won’t upload. Please email if more are required. I have never seen this bug before. Inkerman, Ontario. Canada


Number 7452.     This appears to be a great golden digger wasp, Sphex ichneumoneus (Hymenoptera: Sphecidae). The female wasp digs burrows in the soil that she then provisions with insects (most often relatives of grasshoppers) that she has paralyzed with her sting. These serve as food for her developing larvae. See Great golden digger wasp detailed information .


Lace bug

7451.        Hi, we cannot find this tiny bug ID anywhere. For a size comparison the stitching seen on the photo is the stitching on an IPAD cover. We have lived in Medicine Hat for 50 years and never seen this one before. I hope the picture is clear enough as we had to zoom in and save it as the bug was so tiny. Thanks. Medicine Hat, AB. Canada


Number 7451.    This is a lace bug (Hemiptera/Heteroptera: Tingidae). These are sap feeders, usually found on the underside of leaves. See Lace bug image .

See scarab beetle details on their biology .


Birch catkin bug

7447.      Keep finding these in our motorhome after our trip to the Okanagan, camped under trees. They like the sun and smell a bit when squished. Very small and can fly a bit, hard shell. Surrey, BC. Canada


Number 7447.    The most likely suspect is the birch catkin bug, Kleidocerys resedae (Hemiptera/Heteroptera: Lygaeidae) – see Birch catkin bug detailed information


Adult cicada

7446.       At least 3 cm long. Montréal, QC. Canada


Number 7446.      This is an adult cicada (Hemiptera/Auchenorrhyncha: Cicadidae) emerging from its nymphal ‘shell’; it will gradually change colour and harden its skin over the next few hours, and then fly off in search of a mate. Cicadas of this type often are referred to as ‘annual’ or ‘dog-day’ cicadas, as some emerge every year (usually after midsummer) after spending several years as nymphs feeding on tree roots underground.

Mass of them on concrete foundation. They were not there yesterday. Impressive amount of them. Mont-Tremblant, Quebec. Canada


Number 7444.    These look like nymphs of the white-margined burrowing bug, Sehirus cinctus (Hemiptera/Heteroptera: Cydnidae). They feed primarily on the seeds of plant in the mint and nettle families.



I’m noticing a small dirt pile against my foundation and under the side of the house that was recently repaired for rot. It looks like ants are making their way in between the shell thing patch price under the siding. Is the debris in the dirt pile from the sheathing or dirt under the pavement? Is there a caulking, spray foam, stuffing and or spray I should use here. It only is happening in one spot around my foundation. Thank you kindly. Eastern Passage.

Expanding foam (see for an example) can be used as a barrier to ant entry, but be sure to clear away any loose material (soil, etc.) from around the opening to be sealed before applying the foam. There are foams available that also incorporate an insecticide – see for an example.

Broad-nosed/short-snouted weevil

7443.       Started seeing these a couple weeks ago, mostly in tiled bathrooms and front entrance. No sign of any in bedding , nor no insect bites. They’re very dark coloured—like black. They move slowly. Do not fly. Ottawa, Ontario. Canada


Number 7443.      This is a broad-nosed/short-snouted weevil (Coleoptera: Curculionidae; subfamily Entiminae). They often enter buildings in search of shelter, but do no harm there. See Broad-nosed/short-snouted weevil example .


Assassin bug

7442.      I’ve seen a few of these guys in the summer months. They seem to get in through the window air conditioner. What is it, and is it dangerous to me or my cat? (On that note — please excuse all the cat hair visible in the photo.) Thank you. Toronto, Ontario. Canada


Number 7442.     This is an assassin bug (Hemiptera/Heteroptera: Reduviidae) known as the masked hunter (Reduvius personatus).

See Assassin bug detailed information .



7441.        I have a problem with my apartments not sealing my baseboards and open areas we have bombed sprayed and fogged and they keep getting in Spiders, and roaches. There are 100s outside and I work hard to keep them out my apt but they don’t have proper sealing. Any way is this a roach or a spider. Yuba City, CA. United States


Number 7441.    This definitely is a cockroach; possibly an oriental cockroach Blattaorientalis (Blattodea: Blattidae). See cockroach detailed information .
