Elm seed bug

7429.     Found about 6 of these on my living room carpet this morning, not moving much, some may even be dead; didn’t see evidence of them flying. May 2023 in Vancouver during a very warm spell (27-30C indoors). Largest was about 7mm long. Black/dark brown. Also saw a few similar ones around a window frame of an open upstairs window. Vancouver, British Columbia. Canada

 

Number 7429.      This appears to be an elm seed bug, Arocatus melanocephalus (Hemiptera/Heteroptera: Lygaeidae); a European species that has become a common nuisance pest in the Pacific Northwest. See elm seed bug detailed information .
