Hi,
These small grey ones are too difficult for me. I think this is an anthomyiid. I wonder if a bit more could be said. It is a Berlin fly from last May.
Thanks, Sundew
PS. The arista is plumose.

Cross-veins look a bit darkened - I wonder if this is
Anthomyia liturata?

arista short plumose or long plumose? If it is what I would call long rayed (individual rays few in mumber) it is probably Hylemya variata; if shorter haired (with more numerous hairs) it could be Anthomyia liturata

I'd say it's the first case.

That's short plumose! Arista about the same as liturata, but I still can't reconcile the photo with liturata because the abdomen is almost cylindrical in photo 3 unlike liturata where it is semi compressed. Perhaps in life the abdomen is cylindrical, but in all my dried specimens it is flattened in basal half.

The arista hairs look well-proportioned compared to the arista length, I wonder how a "long plumose" arista would look like...
There are some
A. liturata photos in the gallery that show a cylindrical abdomen, but with a lateral "keel", so that a flattened shape might form when being dried. - I shall label my pics "
A. liturata group", which hopefully covers such variability.
Many thanks for your efforts, dear Michael!
Best regards, Sundew
