Hi,
This Empis from Sunday evening has patterned wings, as shown in the upper picture taken without flash. The fly then flew away to mate, and I got only a few more pictures. - Paul wrote in https://diptera.i...d_id=83929: "Maculated wings, yellowish red coxae, all black antennae: E. maculata". However, I am not sure if the antennae of my fly are completely black. And I did not find a description of E. apicalis, another candidate. So is E. maculata group the most we can say, or can a species name be found? (The location was southwestern Germany, 20 km west of Stuttgart.)
Many thanks for your help,
Sundew

Here is another male from the same day and location, eaten by a crab spider (Diaea dorsata).

I think maculata and variegata are the only two with maculated wings in the subgenus that occur in Germany.

Thanks, Paul! According to Chvala (1994), A. variegata has black coxae that are densely grey dusted, whereas the E. maculata in https://www.bioli...nid=120783 has red coxae like mine. So I think E. maculata is the right name.
