Hello kuv,

I based the id of your photos from the other post, as i do believe that they are of the same species. I did not carefully examine your photos. I usually require reading glasses because my vision is slipping. However, i can clearly see a large pit on the inside of the antennae, which confirms B. panzeri according to various keys. The pit is much smaller on B. dorsata. Microscopic examination is not necessary due to the large visible pit.

see my attached crop of your photo with this diagnostic pit. Also see a magnified pit at spessart website: http://www.spessart-fliegen.de/diptera/syrphidae/brachyopa/brachyopa_panzeri/IMG_2443.html

I do not place ego before science but it doesn't mean that i am absolutely correct. I think that this is Brachyopa panzeri. I also think that the species in the other photos is also B. panzeri: https://diptera.info/forum/viewthread.php?thread_id=92897&pid=385532#post_385532
