Meigenia?
Nikita Vikhrev
Moscow region, 10 aug, 8-9mm.
I've got Meigenia, that pilosa/basignata, both not valid anymore.

Hi Nikita

It is not Meigenia.
Pity we can't see the wing, but my guess is Exorista (rustica-group)
No sure, though

Some day, Theo, I'll learn your Tachinidae.
Venaiton.

Thanks.
It proves I was partly right.

You can see a distinct fold coming out of the bend in vein M.
This is an indication of Exoristini (or several other possibilities).
However, Blondeliini like Meigenia are characterized by a very smooth bend in vein M (quite the opposite).
Moreover, the strong descending frontal bristles always suggest Exorista.

However, I see strong discal setae on tergites.
Therefore, it cannot be rustica.
So Exorista spec.
