Summer Fishfly

7205.    Found on porch, during hot day in May. Haven’t seen one before, it was quite long with fuzzy entente, it was near my front door so just want to be sure it isn’t something to worry about if it gets indoors or if I should take precautions. Hamilton, Ontario. Canada

Brown Scavenger Beetle

7203.       I’ve found a few of these in the bedroom a week after noticing itchy bites that look like bed bug bites, many in a row/cluster pattern. It’s very small (1-3mm long) and although it looks like a bed bug from the bottom, the top view looks very similar to the black carpet beetles we’ve seen downstairs. Is this a bed bug or a carpet beetle that happens to be brown? Aurora, Ontario, Canada

Number 7203.   This looks like a minute brown scavenger beetle (Coleoptera: Latridiidae). Their presence in a home usually is indicative of a humidity problem, as they feed primarily on fungus filaments and mold spores. One species is known to ‘sample’ human skin, but its appearance is quite different from your specimen;  Brown Scavenger Beetle Details

Millipede

7193.        We have been finding a few of these caterpillars in the house. Mostly near the patio door in the kitchen, however, we did see one at the top of the basement stairs. It is springtime now and has been quite rainy for the last couple of weeks. Can you help us identify it and suggest how to get rid of them. Nepean, Ontario Canada

Number 7193.    This appears to be a millipede, an arthropod in the class Diplopoda. These basically are harmless scavengers on decomposing organic matter. but often are considered nuisance pests when they occur indoors. They require a moist environment in order to thrive, so moisture management is the best control. Keep indoor humidity levels as low as practical, and eliminate as many unnecessary sources of moisture as possible, including leaky pipes/water taps, condensation from refrigeration/air-handling units, etc.

Male spider

7192.     We have found at least 20 of these in the last few weeks since moving into our home in Carlisle, ON. They vary in size, this one is about an inch long in total (legs and all). My husband said he saw one much bigger. Noticeable large bobbly things on its head (excuse the lack of proper terms) What are they? Are they dangerous? only seems to be in one room in our basement. Carlisle, ON. Canada

Number 7192.      It is a male spider; the “bobbly things” are its pedipalps, used to transfer its sperm to a female spider during mating. The image is not clear enough for, but it likely is a wolf spider (family Lycosidae). These are active hunters that often enter buildings during their searches for prey. They are not dangerous to humans.

Colour morphs

7189.         Only submitting because I looked it up and it did not say that these spiders are found in Canada! I found this one on Vancouver Island, British Columbia! I think it is a Johnson jumping spider- just want to know if maybe it’s a new spider to be found in BC? Duncan, British Columbia Canada

Number 7189.     It does look like one of the colour morphs of Phidippus johnsoni, and that species has been reported from British Columbia –  Color Morphs Detailed Information

Nymph of an assassin bug

7188.       Hi, and thank you for helping with this. On our apple tree today (4-28-2021) in Rochester , NY I saw two of these “pollinator assassins” capturing, killing and then ?sucking body fluid from small pollinators. What can you tell me about them and about the range of harm to pollination? Thank you! Honeoye Falls, New York United States

Number 7188.  This is a nymph of an assassin bug (Hemiptera/Heteroptera: Reduviidae) in the genus Zelus. These are opportunistic predators on any other small invertebrates (usually other insects) that they are able to capture. Although they are quite widespread and common, they are unlikely to have a significant impact on pollinator populations.  Assassin Bug Detailed Information 

Dirt-colored seed bug

7187.     Found indoors in April. Seems to prefer crawling as opposed to flying. Sitting on 1/4” graph paper. Armstrong, BC. Canada   Hi, It was crawling on our rug and it was around 3 mm in length. North York, Ontario Canada

Number 7187.    This appears to be Rhyparochromus vulgaris, a dirt-colored seed bug (Hemiptera/Heteroptera: Rhyparochromidae). This is a European species recently introduced to western North America.

7186.      Hi, It was crawling on our rug and it was around 3 mm in length. North York, Ontario Canada

Number 7186. This is a carpet beetle (Coleoptera: Dermestidae) in the genus Attagenus (black carpet beetles and allies). The adult beetles do no damage, but their larvae can be quite destructive.  Carpet Beetle Larvae Image 

Springtails – Collembola

7185.       Outside all over deck railings. Bundle in big groups together. Slow moving. Don’t seem to like direct sunlight. Pointe au Baril, Ontario. Canada

Number 7185.     These springtails, primitive arthropods in the order Collembola, closely related to true insects. These basically are harmless scavengers on bits of decomposing organic matter, but they can become nuisance pests when they occur indoors in large numbers. Yours appear to be in the family Poduridae. Springtails Detailed Information

Nymph of an assassin bug

7184.      This guy was in my house hiding in the load of towels less than an inch long. Soft body no wings brownish in color. What type of bug is this. Winnipeg, MB Canada

Non-biting midge

7183.       Very small fly/moth? that I have recently started to find in my house. Seem to come out in the evening and are attracted to my living room lamp light. They just hang on the walls. Seem to multiple quickly as there were at least 10 last night. I can’t seem to find them in the day. Have translucent looking wings with a reddish head. VICTORIA, British Columbia Canada

Number 7183. This is a non-biting midge (Diptera: Chironomidae). If you live anywhere near water, you likely will be seeing a lot more of these as their larvae are aquatic, like their cousins, mosquitoes.

Broad-nosed/short-snouted weevil

7182.     Hello, we found a few of these bugs in our home on the walls. We would appreciate it if you could identify the insects, explain if they are dangerous and how we can ensure that they will not reappear. We do not know where they are coming from. Thank you, RICHMOND HILL, ON Canada

Number 7182. 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. Short of hermetically sealing your home, there simply is no way to ensure that you will not receive more visitations.

Brown marmorated stink bugs

7181.    Hi, I was just wondering… Are these stink bugs doing what I think they’re doing? Are they propagating the species? Pelham, Alabama United States

Number 7181.  If you mean mating, yes they are. Also, they are brown marmorated stink bugs, Halyomorpha halys (Hemiptera/Heteroptera: Pentatomidae). This is an introduced species that has become a pest, primarily in orchards, in many areas of North America. They will come indoors in search for shelter, but do no harm there.

Cockroach

I live in an apartment and I feel like there may be something fishy about what the pest control company is doing. 2 months ago they checked all suites. When they came to ours, which was cleaner than clean, and we just emptied the trash an hour before, the man magically found ONE cockroach in the garbage can and claimed we’re infected when we’ve never seen them before, and never again afterwards but for some reason now, 2 months later they wanted to spray poison around our suite even though there is no physical evidence of any pests here. We had kicked them out on their visit yesterday for unrelated matters of them using homophobic slurs and making pedophiles jokes when they thought we weren’t around, BUT I want to know if there is a reason to want to spray poison like that for finding one cockroach in our suite 2 months ago cause I’m sure our landlord will be approaching us soon. Duncan, BC

If your account of events is accurate, it is unlikely that you have a cockroach problem serious enough to require professional intervention. However, just to be on the safe side, I suggest that you procure a few sticky traps (‘Roach Motels’) and place them in your apartment according to directions. If you do not catch any cockroaches within a few days, that should confirm no need for control.

Larva of ground beetle

7180.      Beetle larva. London, Ontario. Canada

Number 7180. This appears to be a larva of a large species of ground beetle (Coleoptera: Carabidae). These are general predators on other small invertebrates, primarily other insects. Ground Beetle Detailed Information

7179.      I suspect a giant water bug but would like confirmation. No ponds or standing water nearby. Strathroy, Ontario. Canada.

Number 7179. It certainly is a giant water bug (Hemiptera/Heteroptera: Belostomatidae). These are strong fliers that may be found far from any water source. Giant Water Bug Detailed information 

Western conifer seed bug

7178.      I m just wondering what kind of bug this is. It was found in PEI in someone’s house. Crapaud, PEI. Canada

Number 7178. This is a western conifer seed bug, Leptoglossus occidentalis (Hemiptera/Heteroptera: Coreidae). Although harmless, these can become nuisance pests when they enter homes in search of shelter. Western Conifer Seed Bug Detailed Information

Number 7177. This appears to be a drugstore beetle (aka biscuit beetle), Stegobium paniceum (Coleoptera: Anobiidae). These beetles will infest an extremely wide variety of dry stored food products, including cereals, flour, baking mixes, spices, drugs, pet foods, etc.  Drugstore Beetle Detailed Information 

Young nymph of a German cockroach

7176.      I found this on the wall in my bathroom this morning. Could you please identity what it is? Toronto, Ontario. Canada

Number 7176. The image is not clear enough for a confident identification; it might be a very young nymph of a German cockroach, Blattella germanica (Blattodea: Ectobiidae), a peridomestic species difficult to bring under complete control.  Cockroach Control Recommendations

Predaceous diving beetle

7175.        Large black beetle ~ 1.25-1.5″ tracking along the water’s edge — south shore of Wolfe Island (Lake Ontario) only one seen along the length of the beach 25 Mar 21 mid-afternoon. KINGSTON, ON. Canada

Number 7175. This is a predaceous diving beetle (Coleoptera: Dytiscidae); likely in the genus Dytiscus. They along with their larvae (’water tigers’) are voracious predators on other small aquatic life forms. They are strong fliers that often are found far from any water source.
