I have a number of these bugs in my bathroom - they have wings, look a bit like ants and they seem to be neverending...They only appear in the spring/summer, and they seem to congregate particularly on the sink and around the window, they seem to end up on the ceiling too. They vary in size from tiny to about 1cm in length. Sometimes they look like they have tails, but the one in this picture doesn't seem to have one.
Any help greatly appreciated..they are driving me mad! Sorry the pictures aren't great.
Hi Nic, I have no idea what these are, but am pretty sure they are not what one might categorise as a "household pest". I suspect the ones that have "tails" are females with a long ovipositor (egg laying device). I'd suspect a small sawfly or similar .... but I really don't know. With luck, one of the experts will be able to help.
It is a wasp (Hymenoptera) but (if you ask me to make a guess) it belongs to Apocrita, not Symphyta (Sawflies), as it have a waist. I'm no expert on hymenopterans, but I guess it belongs in Ichneumonidae, a family of parasitic wasps with an immense number of species all looking exactly the same...
On this link there is a key to the subfamilies of Ichneumonidae, which very much explains why I find them impossible to identify -not only, but especially, from "blurry photos" (no critic intended!).
Thank you Big Ma and Episcophagus! In my insect ignorance, I am really surprised to hear that they are wasps. I will check out the link you sent, thank you...(and work on my close photography skills).
I am the last person you'd think would be researching insects, but have become quite obsessed!
