Hi, yesterday I took a few pictures of a small greenish fly with a metallic tinge. I would suspect, that it is a male of Dolichopus sp.. Is that correct and/or is it possible to determine the species from the pictures? Germany, Southern Bavaria, Munich (-West), shrub leaf, 16.06.2024, app. 5 mm Greetings, Uli ukursawe attached the following image:  [292.02Kb] Edited by ukursawe on 19-06-2024 08:53 |

Hercostomus nigriplantis? Note the enlarged mid fifth tarsomere. |

Hi John, thank you very much for the determination. Do you think that could go without a cf.? I don't have the experience for this kind of determination, but the three criteria listed in the "Grichanov Checklist & keys" seem to be met ("Mid basitarsus without ventral setae; scutellum bare dorsally; 5th segment of midtarsus slightly dilated;").

The key by Grichanov is for Europe north of Germany. I do not know if there are any similar species in Bavaria. |
