Predaceous Diving Beetle

6405.  The bug on the wall of house flys and bites. Winnipeg, Manitoba, Canada

 

Number 6405. This is a female predaceous diving beetle (Coleoptera: Dytiscidae). These are general predators on small aquatic life forms; they are strong fliers and often are found quite some distance from the nearest water. Their bite is harmless.

Metallic wood boring beetle

6400  Not sure what type of beetle this is. Carleton Place, ON. Canada

 

Number 6400. This is a metallic wood boring beetle (Coleoptera: Buprestidae) in the genus Dicera, Click here for an example. Their larvae often are called flat-headed wood borers because the area immediately behind their head usually is much wider and flatter than the rest of their body. Some species can be serious timber pests.

Rove beetle

6366  May 15 2019. It’s been rainy and the ground is moist. I have an outdoor pen for my indoor cats so that they can be protected while outside. I found about 12 of these very small insects on my cat who came in from the garden behind our house. They are very small about a cm or so and moved quickly. I first thought they were small black seeds but then they started wiggling on the brush, like small ants and moved quickly on a piece of kleenex. They seemed to be making her scratch. Are these Rove Beetles? From: Guelph, Ontario N1C1E3 Canada

Number 6366 This is indeed a rove beetle (Coleoptera: Staphylinidae). As you likely already know, these are general predators on other small arthropods, and should cause no harm to your cats.

Carpet beetle

Number 6362 This is a carpet beetle (Coleoptera: Dermestidae), possibly a varied carpet beetle, Anthrenus verbasci. Click here for detailed information and Click here elsewhere on these pages for some control suggestions.

Foreign Grain Beetle

6226 I took photos of this insect on my bed today (May 31st, 2018). Lately the weather has felt like summer. I’ve started noticing them about a week ago and mainly on and in my bed, maybe 1 or 2 at a time. As I would start falling asleep, I would wake up and find one on my pillow. So far I have no bites, hives or itchy spots. I removed my bed sheets and there are no bug infestations or blood stains. Yesterday I just kept seeing them in almost every room of the house (floors, walls, ceilings, bedding, etc.). They are tiny and much smaller than an apple seed. All the ones I’ve caught look the same. I’m wondering if they are an early stage bed bug. How do I get rid of them? From Ottawa, Ontario

Number 6226 – This appears to be a foreign grain beetle, Ahasverus advena (Coleoptera: Silvanidae). Sometimes also called new house beetles or plaster beetles, they feed primarily on mould/mould spores found in humid/damp environments. Reducing indoor relative humidity levels should control them. Click here for more detailed information
