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. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Hello, crex and Nikita! Nikita Vikhrev wrote: 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.

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. |

Hello, Paul! Paul Beuk wrote: The top one might well be a species of the Drosophila obscure group. 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.
