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. Petr Michael attached the following image:  [153.67Kb] |

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. Edited by Jaakko on 25-11-2009 15:55 |

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! |
