Hello,

Found this little (6-8mm) black Syrphid with hairy shoulders.

It was cleaning its head, so one can almost see its face on this picture. I find that the face is rather hairy without any knob. More, the front legs are not black.

Is it possible to ascertain the species?

Hello,

Nobody has the slightest idea?

Thanks in advance.

Hello Pierre,
Not Pipiza, because their forehead would protrude conically, that would mean that you would see on a photo like this (the first one) a bigger bulge where the antenna is situated. Also Pipiza would normally be a bit bigger a guess, this one seems rather small.
This looks to me like a male in the genus Heringia (Neocnemodon is the old name)! Wink
Greetings, Gerard

Hello,

Looking in the books of Stubbs and van Ween, it seems me that the third antenna segment is rather oval, this would mean Heringia (Heringia) and not Heringia (Neocnemodon).

If this holds true, since H. senilis is treated as a synonym by van Ween and as a "taxon of uncertain status" in Fauna europaea, we should conclude: Heringia (Heringia) heringi.

On the other hand, the picture was taken in Paris on October the 31st. Is that not a little late?
