Sphaerocerid Sphaerocerid

cf. Spelobia
Could be a Spelobia, but it isn't an easy call.

Moved from Lesser Dung Flies.

Possibly Coproica
Possibly Coproica.

What other details are needed
for sphaerocerids? I have some other shots of this one.

Coproica has typical wing veins for Limosininae (M and CuA1 ending far from wing margin) and many (10+) little hairs on the top surface of the scutellum. They are associated with dung. Species that like farm animals are more widespread than species that prefer wild animals.

More photos
I just added a washed-out dorsal shot of the same individual. In a moment I'll upload some better shots that were taken at the same time, not necessarily the same individual. This was on dung in a forest; I don't remember now what kind of dung it was, but it's possible it was horse dung.

Not Coproica
This is not Coproica or Leptocera, and there are only a couple dozen genera left it could be.

Didn't think the scutellum matched your description.

Moved from Flies.
