Hello!
These flies with the size of house flies sunbathed on leaves at a woods edge in Ostwestfalen/Germany yesterday. I think, they are Tachinids, but I can't find which genus. Can anybody help me? Thanks!

Anyway we wait Theo.
Meanwhile I check myself.
M not bend to R, than it isn't Tachinida.

Right, Nikita !
It is a Muscidae (or Anthomyiidae or Fannidae).
So it is not in my league.
Good luck !
Theo

Thanks Nikita and Theo! So it is another example that not all flies with thick, stiff hairs on the abdomen are Tachinidae...

And vice versa: not all Tachinidae are very bristly (many exceptions in Phasiinae).
Nevertheless, to a Tachinologist's eye your flies are 'just' hairy and not really bristly !
The main point is the bend in vein M:
Virtually all Tachinidae have this bend (and virtually all Sarcophagidae and Calliphoridae),
and only a very few Muscidae that are easily recognized (Musca, Graphomyia and a few others).

Yes, I know the importance of the wing venation for identification. I sometimes neglect it, because it is often not well recognizeable on my photos, especially when there are light reflexions on the wings.

I would not be surprised if someone gives Helina evecta as ID. Look at the abdominal squarish spots on T3 + T4. I have also the impression of 4 postsutural DC bristles. Unluckily, the picture is not very clear. Jan HC Velterop

Five years !
I would not be surprised too (though the very similar but rarer
H. annosa can't be totally excluded). ;)
