I think, they are Tachinids, but I can't find which genus. Can anybody help me? Thanks!

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

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.
