In the keys, forked/not forked media is the first step in the determination of this family, distinguishing Sciapus from other "dolis", Anyway, I am not a specialist...

Thanks, Jan and Jürgen, for your ID help!
Is Chrysotus sp. more likely?
Best regards,
Volker

Diaphorinae. The distinction between Chrysotus and Diaphorus is often unclear. I don't know how it works in Europe.

Looks to me like Chrysotus sp. (at most 3 mm long). Female a little longer.

Thank you, John and Igor, for your ID help!
Unfortunately, I could not measure the size of the fly. My estimate might be somewhat too large. Anyway, it was a small fly with remarkably iridescent wings.
Best regards, Volker
