Hi,
According to the partly yellow antennae and the short first antennal segment I consider this male Empis scutellata. As far as I know there is no other member of subgenus Xanthempis that has such antennae. Seen in southwestern Germany (50 km west of Stuttgart) on 12th June.
Thanks for comments, Sundew

Dear Igor, what a surprise! So this yellow one belongs to Leptempis. The species is said to be rare and endangered in Germany. I do not know any literature about it; is there a European Leptempis key where it is included? In Chvala (1994) it is not mentioned.

Hi,
There is no modern key for this complex of species. It includes three very similar European species (all with yellow mesoscutum and a median vitta): E. dimidiata Mg., E. mesogramma Loew and E. divisa Loew. You could find them in Lindner's "Die Fliegen, S. 401" (Rhagionempis =Leptempis), where E. monogramma Meig. = E. mesogramma Lw. and E. scutellariae Bezzi = E. dimidiata Mg.
Best wishes,
Igor

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
