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.
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
weather: low temp 20 degree c.
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
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 https://tinyurl.com/yaa2l9g3 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.

6164 Found this live bug this morning (5:30am) on my bathroom mat, I am location in Brampton, Ontario, Canada. Legs would tuck in when prodded, then after few seconds get up and move. Moves pretty quickly. Size is approx 4mm from tip of head (not antennae) to backend. The weather is just starting to here to single digits (celcius) in the morning. I have seen this bug dead before (about 5 of them) in the bedroom near the mattress, and once on the mattress when I was changing the sheets, they were all dead. Would like to know what this bug is and if I need to take action. With kind regards, Amy
This is a click beetle (Coleoptera: Elateridae), it appears to be in the genus Aeolus – see https://tinyurl.com/y8lo5jr7 for an example. These simply are accidental intruders that will do no harm. Ed Saugstad, retired entomologist; Sinks Grove, WV.
6163 This was on the roof inside our holiday trailer on August 28, 2017. It was about 5/8” in length and 3/8” wide. When my husband picked it off the ceiling he said it wouldn’t “squish” in between his fingers because the body was hard. We were camping at Tunnel Mountain Campground, in Banff, Alberta. Neither of us have seen a bug like this before, so thank you for identifying it for us. Mary and Garry
This appears to be a red-cross shield bug, Elasmostethus cruciatus (Hemiptera/Heteroptera: Acanthosomatidae); see https://tinyurl.com/ybfqbwfy for an image. They appear to feed primarily on alder trees. These are very close relatives to true stink bugs in the family Pentatomidae, and sometimes may be mistaken for one of those.

6162 Hi. This beetle was found in field behind my house on a sunny day during mid-October. I live in Port Elgin, Ontario. I don’t remember ever seeing this beetle before and didn’t see it on your website. The beetle is fairly large at around 3.5 cm long. My son has suggested that it may be an Oil beetle. Please confirm. Andy. Port Elgin, ON
This is indeed an oil beetle, a type of blister beetle (Coleoptera: Meloidae) in the genus Meloe. They are called oil beetles because of their habit of exuding an oily fluid (their equivalent of blood) from between their joints when handled roughly. This fluid contains a chemical (cantharidin) that can cause blisters on tender skin. See https://tinyurl.com/y7jhuhrq for more information. Ed Saugstad, retired entomologist; Sinks Grove, WV.
6161 Please help with ID of this guy. My son found him already dead. It looks like a borer of some kind but I cannot find it online anywhere. We live on the edge of a wooded area, and just received a load of wood from a local source in the last 2 weeks. Thanks, Jennifer. Just outside of Greater Kingston Area, Ontario, Canada.
This appears to be a brown prionid, Orthosoma brunneum (Coleoptera: Cerambycidae), see https://tinyurl.com/y7tpzvhg for an image. Their larvae bore in damp/rotting wood, usually that in contact with soil; they are not destructive. Ed Saugstad, retired entomologist; Sinks Grove, WV.
6160 Location: Valleyfield, Quebec, Canada. Place fund: book store, build on a concrete slab. We had the insects showed in post 5612. But they evolve into this and they still move really fast. They now measure about 5cm long and when they flee they’re about 2cm tall. We would like to know what are those bugs and can they bite or damage any goods in the store ? There is no food, it’s a book store. Thank you. Rachel O.
This is a house centipede, Scutigera coleoptrata (Chilopoda: Scutigeromorpha), a peridomestic species having a very wide distribution. They cause no damage, but feed on other arthropods that they happen across. Although the house centipede is capTable of biting a human, this seldom occurs, and the effect of a bite reportedly is no worse than a minor bee sting.

6152 Hi, I’m curious if you might be able to identify this insect. The picture was taken late August 2017 in the Vancouver, BC Canada area. The insect seemed to have sticky pads of some type on it’s “feet”, as it wouldn’t easily come loose when the cup was repeatedly shaken/banged outside, until it flung (didn’t fly) and stuck/grasped against the side of the nearby house about 4’ away. Any help would be appreciated. Thanks, Jason

6150 I found this caterpillar in Weldon Park in London, Ontario a week ago (late September). Is it a banded tussock? I’m curious to know what the white things are on it’s back. Kelly
This does appear to be a banded tussock moth caterpillar (Halysidota tessellaris; Lepidoptera: Lymantriidae). The white objects are the cocoons spun by larvae of a parasitic wasp (likely a braconid in the subfamily Microgastrinae) that developed within the body of the caterpillar. When the larvae are fully grown, they chew through the cuticle of the caterpillar and then spin a cocoon that protects them during their pupal stage. Ed Saugstad, retired entomologist; Sinks Grove, WV.
I am from Toronto, I found this thing walking around my bedroom. It is about one cm.
6149 This is a short-snouted/broad-nosed weevil (Coleoptera: Curculionidae; subfamily Entiminae), likely a black vine weevil (Otiorhynchus sulcatus). Adults will occasionally invade homes but they cause no harm there. See http://tinyurl.com/monvaej for detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

6134 Hi. This bug was just inside my house in Nova Scotia. Is this a form of tick?
This is a masked Hunter. Both adults and nymphs are predators that feed on other insects including flies, carpet beetles, mealworms and bed bugs. The adult bug is dark brown or black and about 3/4 of inch long. The nymphs or immatures are covered with microscopic hairs which catch and hold dust, lint, and other small particles of debris.
