Hello I caught this fly 2 days ago in a alkaline fen. It is an Ogcodes and to know the species I tried to use Faunistik und Taxonomie der Acroceriden (Diptera) der Schweiz by M. Weinberg and G. Bächli. I think I'm not wrong if I say it's a male. I mainly hesitate between O. gibbosus and O. zonatus but I think it is more likely to be the first species. I don't know if the halter is white enough for gibbosus and I'm not sure to well inderstand the part about "Schüppchenrand". But the legs color doesn't match with pallipes I think and the hind femora et tibias are too straigh for a male zonatus. What do you think about this fly ? I can do other pictures of the fly if necessary. Found in "Marais d'Episy", Moret-Loing-et-Orvane, Seine-et-Marne, Île-de-France, France On the 2nd of July 2022 Body length : 6 mm Axel D attached the following image:  [171.66Kb] Edited by Axel D on 06-07-2022 14:31 |

Yes, I agree. Pallipes is much darker tergites. Yellow halter clearly supports gibbosus. Well documented ! Theo |
