Hello kuv,
All is good. I'm happy that you have an id. I like Brachyopa. I find them to be most interesting from this family (Syrphidae.) Anyway, i did some more research on the black bristles of the scutellum and i discovered that Speight uses this feature in his keys to Brachyopa: https://diptera.info/downloads/StN_KEYS_Glasgow_2011.pdf
So it is a valid method of identification. Speight is a leading expert of Syphidae as far as i know. My first post should have ended the conversation.
Thank you Xylo. Thank you Ectemenius.
Best wishes,
John
