Thread subject: Diptera.info :: All Sphaeroceridae?
#1
Hello, forum!
Are these two tiny flies (pic 2 and 3 should be same species) all
Sphaeroceridae? No. 1 was about 2 mm long, no. 2/3 only slightly larger. Most obvious difference: clear resp. shaded wings.

The dull dark grey thorax and M on head I believe is characteristic for some genus. I would have searched the forum for it, but diptera.info is so incredibly slow these days.

I think the last two are
Desmometopa sp (Milichiidae).

No, the last two is Sphaeroceridae.
The first one isn't Sphaeroceridae.

Thanks! The more often I watched the first photo, the more I also had come to the conclusion that that fly must belong to another family. But which one???

The top one might well be a species of the
Drosophila obscure group.

How do one see the difference between Desmometopa (Milichiidae) and Sphaeroceridae? The only thing I can come up with is the scutellum seems more elongated on the latter. They both are small blackish and have dark thorax with contrasting grey hairs, long arista etc.

Interesting! It reminded me of Drosophilidae from the general habitus, but I had never seen such a dark member of that family (the
D. subobscura in the gallery doesn't seem so black).

Lateral and dorsal view may make a difference in how 'light' and 'dark' are perceived. There appears to be some clouding near the apex of R2+3, so it might be
D. obsucra itself.
