Hello, is this a Brachypalpus, maybe B. valgus? Found today and yesterday (24-03-2017, 25-03-2017) on Willow (Salix) in the Elbe River floodplains, Lower Saxony (first two photos one individual, photos 3 and 4 another individual). (there was no comment in the main forum, so I try again here. Additional photos here: https://diptera.i...d_id=78530) best wishes, Jann Jann Wuebbenhorst attached the following image:  [94.58Kb] Edited by Jann Wuebbenhorst on 27-03-2017 19:35 |

I think you are right. Brachypalpus laphriformis has a dark arista, while B. valgus has a white one. Chalcosyrphus eunotus is also similar, however, it has a dull thoraic dorsum, while your specimen has a shiny one. On top of that, B. valgus is a spring species, Chalcosyrphus eunotus is not. |
