Hello, my pictures are from June 6, 2022 in Hannover,Germany. It was at our garden pond with a lot of Juncaceae. Could it possibly be a Cerodontha bimaculata? Many thanks from Hans Haleun attached the following image:  [284.07Kb] Edited by Haleun on 25-09-2024 17:31 |

I agree with subgenus Dizygomyza. Cerodontha bimaculata is supposed to have wing membrane darkened. |
