This hoverfly species was photographed near Bezbog in Bulgaria on 6 August. I had initially thought that it might be Scaeva selenitica however our County hoverfly recorder advises me that "the proportions don’t look right for the genus, with the head not looking particularly large, the abdomen rather dumpy, and the wing not showing a “step” in the wing-vein R4+5 (the vein second below the stigma)". He suggests that it might perhaps be from the genus Dasysyrphus.

I would welcome any suggestions as to the identity of this species. I do have the specimen.

Many thanks

Alan

Hello Alan,

This is indeed a Dasysyrphus. The Black antennae and the constricted abdominal markings make this, in my opinion, D. lenensis.

Hello gentlemen,

I looked at the key in van Veen since D. friulensis is unknown to me. And it is indeed a female D. friulensis. Antennae black and margin of abdominal tergite 3 and 4 yellow and black.
D. friulensis is a mystery species. The species was first recorded in The Netherlands in 1959 but last seen in 1989. Since then there have been no further sightings.

Greetings,

Ectemnius
