These flies were really abundant in a cave we visited on weekend (7th February). Also, there were a lot of pupae also, on the walls of the cave and on the floor also. This is quite a long and big cave, and the flies were mostly near the entrance. Can someone determine them?

Do these pupae belong to these flies?

Thank You! What characters are needed for further ID? I have a specimen.

I looked it up in a checklist and from this cave three Heleomyzids are recorded: Gymnomus caesius, Heleomyza captiosa, and Heteromyza atricornis. I think than it must be H. atricornis. Can anything be said about the pupae?

Hello,
because Andrzej is busy, i try to say somethink about your flies. I think it is not possible to determine species from these photos (I need frontal view to mail), but from caves I know only H. atricornis (my own experience and literature too).

Attention please !. The gena is very small (you can compare with specimensof H.atricornis from the Diptera Gallery). Hmm... It is better to ID as Heteromyza sp. Andrzej

Hello Andrzej,
I dont understand your attention:o. The gena of Heteromyza males are always smaller than females. In diptera gallery are only females and i think the third photo from pwalter is a male.
