Hello Andrzej & Dick,
My suspicion is that it concerns Tephrochlamys rufiventris, but I have only a female. Another is the female of this observation:
https://waarnemin...w/98060383 which has, like the specimen shown here, black antennae. In other Diptera, like the syrphid Episyrphus balteatus, darker specimens occur in winter. Thus far, all the observations of grey abdomened and black antenna Tephrochlamys c.f. rufiventris are from either December or January. I'm curious if this is a male (seems to be) and what you will find Andrzej!
Kind regards,
Ectemnius
