IMHO, Scaptomyza has much longer wings and in general, an "anthomyzid" appearance. It looks like the fly has 4 acrostichal rows of setulae and 2 ventral branches on arista. If so, this is a Drosophila sp. ex obscura group. The rest needs dissection of terminalia.

Agreed with the chaetotaxy. I do not have any references concerning this family. So, this is another Drosophila. Next time I will collect it.

No, this is Scaptomyza graminum. Drosophila does not have such striped pattern on the mesonotum.
