Hello everyone, I photographed this little fly today in southwest Germany on the bank of a stream. Is it possible to determine it? I estimate the size at 3 to 4 mm. Greetings Siggi Siegfried Rudolf attached the following image:  [176.87Kb] Edited by Siegfried Rudolf on 09-09-2023 08:36 |

Difficult to be sure which species you are dealing with. It belongs to the group including Geomyza annae/G. balachowskyi/G. hackmani/G. martineki. The dark subscutellum would indicate this is not G. balachowskyi. Wing is a bit wider in G. martineki, compared to the other species, but that's difficult to properly judge. Did you collect the specimen?

Hello Jan, please excuse my late answer. Thank you for the additional information. They are very interesting to me. I didn't collect the animal. I just take photos. Greetings Siggi |
