Phoridae, I think (I'd better add)

You are quite right, crex, the pupa itself would have been enough.

A Megaselia, I think - a number of species breed in dead insects (though very many are parasitoids). As it is a female, it's going to be difficult to ID with certainty.

Thanks Crex, Paul and Tony! I've got a lot more of them, they live in a wasp nest I recieved. Maybe a picture of a male will be decisive? If only I could see the difference between male and female, they're so small... This is an other one, is it male??

That also looks like a female - even with the males it's usually necessary to slide-mount the specimens to see the detail to enable specific identification. Megaselia is a "super genus" with hundreds, perhaps thousands, of species. A few have distinctive characters which enable easy identification, but most are rather difficult!

Tony, thanks for that information. I'm new at this and don't know what's posible and what's not. Kind regards, Sandra |

The latest estimate (guesstimate really) of the total number of Megaselia species wordwide is 'at least 15,000'  Europe alone has probably 1000 species, and Megaselia is by no means a eurocentric genus... Kahis |
