Hi, I found some of these flies on a dead aspen in June and July 2022 in Germany, Saxony. I guess Strongylophthalmyia ustulata. Am I right or could it be another species? Greetings, Marion Marion Friedrich attached the following image:  [182.09Kb] Edited by Marion Friedrich on 25-08-2022 21:56 |

What about Psilidae?

Hi Jürgen, thank you for answer. I found this old thread https://diptera.info/forum/viewthread.php?forum_id=5&thread_id=53383 Psilidae I can´t exclude, but Strongylophthalmyia ustulata was the best matching species for me. I observed the flies on a thick stem of a dead aspen. Most of the Psilidae larvae should be phytophagous on nonwoody plants. Best regards, Marion |

I agree, Strongylophthalmyia ustulata https://micropezi...my/term/55 and Krivosheina's 1982 key is at https://micropezi...fo/node/85 It would be most useful if you could also add this to iNaturalist then it will end up on GBIF where it will help complete the picture of its geographical distribution in Europe (https://www.gbif....es/1566830) A good find.

Thank you very much for confirmation of Strongylophthalmyia ustulata and the links, Darwyn. Unfortunately, I am not familiar with iNaturalist, but you can use the data with the photos. The pictures were taken in Germany, Saxony, Chemnitz, Harthau on 04.07.2022 (1), 28.06.2022 (2), 25.06.2022 (3) and 11.07.2022 (4). Greetings, Marion |
