I'm afraid species level is impossible: Sarcophagidae, Sarcophaginae - that is all. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Ok, thank you. I wonder what would make it recognisable? Micropreparation and inverstigation of male genitalia. In case of female - rearing eggs, ID male (see above) and than you will get famale of known species.

You might catch some nice feature of the family, you might get some very nice pictures and you might you pick that one species that does have that special something that makes it identifiable. Also, it gives an impression on where the species can be found (at least if the pictures are under natural conditions), positions they take, etc. And youcan always try to catch it afterwards and get it identified.

Not so negative. This case might be an exception. The arista is ... bare ?? At least, it looks bare (could we get a closeup ?) In that case it is not Sarcophagini, but Wohlfartiini. In most cases... Brachycoma devia. In which case the palpi should be dark, as in (most) Sarcophagini. If the palpi are bright yellow, we are dealing with Eurychaeta ( = Helicobosca). Hope this helps Theo Zeegers |

The arista seems to be without hair even if it is hard to tell from this poor close-up.

And the palpi are dark. So Brachycoma devia it should be. Parasite in nests of bumble-bees. Theo |
