Hi,
Today I saw some Choerades flies on the eastern outskirts of Berlin. I suppose I found male and female. They seem to differ from my Ch. fimbriata in http://diptera.in...ost_263225 in that the facial hairs are white and the scutellar bristles dark. The anepisternum is greyish-tomentose, and I do not see yellow hairs. The first antennal segment is rather long. The key leads to Ch. femorata, but can the tergites be so golden-haired? Even in the male there is a golden gleam below the wings viewed from above. So I need an expert's opinion - thanks for any help!

This is the female, eating a Mirid bug, probably Megaloceroea recticornis. Unfortunately I got only this view.

This should be its male (or not?).

I think both belong to that C marginata/femorata/ dioctriaeformis complex

Many thanks, Reinoud - obviously it is difficult to discriminate between these species basing on a photo.
