Would this be Dasypogon diadema (female)?
loc.: shore of Lake Kerkini, eastern Macedonia, Greece

Thanks for your advice.

Most likely not (not recorded in Greece and looks too different). But it is a female
Dasypogon sp. for sure.
In Greece you have:
melanopterus,
gerardi,
kugleri,
octonotatus and
tsacasi.
Reinoud IDed a rather similar one as a possible
D.octonotatus not long ago:

But again, it is a very difficult genus that needs male genitalia for a positive ID.

According to Tomasovic 1999,
D. diadema is more a Western species. Unless it has been discovered in all those eastern countries in recent years, which also can be.
But your fly doesn't fit the description of
D. diadema, (which is a very variable species in colours by the way, but I have never seen such an aberrant colouration in that species) and fits rather nicely that of
D. octonotatus. However I am totally unfamiliar with the species of Greece so I feel a bit uneasy giving an opinion... Sorry I cannot help you more.
