 I think Sarcophagidae: three stripes on thorax, right-angled bend in vein M, and hairy parafacial.

 Actually, looks like a Macronychia. Can we see the abdomen ?

 If I follow Verves & Richet 2009:

Ovipositor inconspicuous, retracted -> 5
1st + 2nd abdominal syntergite with strong mediomarginal bristles -> 6
Parafacial with 1-3 irregular vertical rows of setae -> M. agrestis

Is it possible to determine the species based on these steps?

Thank you

 With current knowledge, yes. But the agrestris/ polyodon complex is a bit of a mess (to me, at least)

I will try to fix the messages this month. We have to make some other configuration changes before software goes out of support at end of year.
