This society was close to the rotting decomposing fish at the bank of sewage pond. Together with some Graphomyia and phorids there were the small black flies - of what family and genus?
Help me! 24th of August, Czechia.

These look quite similar to the
S. nigripes in your second photo.

Dear colleague Jaakko,
thank you very much for having a look at the small flies. In this case, however, I cannnot
agree: there are differences in C et Sc, antennae color, frons width etc. I inclose the new
photo of Stearibia n. in order to elucidate it.

You're absolutely right...
I'm not really an expert on these guys, but besides
S. nigripes I have similar looking Sepsiidae,
Nemopoda nitidula collected from the same substrate. So I would go for Sepsiidae, however I'm sure there are other options for the species.

I am very grateful for that you show me the right way!! As for those flies they are Sepsidae,
I suppose from the genus Themira. One has to learn for ever..... Once more, thanks!
