Eristalis to identify.. - Eristalis obscura - Female
East Angus, Quebec (near Vermont), Quebec, Canada
July 3, 2010
Hello all,

Here is a female Syrphidae photographed in Quebec, Canada (near Vermont, USA) in July 3rd, 2010. I think it is from the genus Eristalis but not totally sure.

Can you help please to identify it (Genus, species)?

Thanks again for your precious help :)

Martin has looked at this one again and points out what appears to be dusting on tergite 4. Although the antennae appear black, it could be just the light in this photograph, so this staying in Eristalis obscura.

I`ve had a second look at this one. Black antennae, obviously hairy eyes, very elongate black pterostigma. Very dark just above wing bases. Could it be Eristalis rupium?

Hello Bill,

Looking on the Internet it seems that E. rupium is an European species (not present in North America).

Hi Michel,
It is on the North American checklist. How correct are the records, I don`t Know but it has been recorded in B.C., Manitoba and New York according to my search. There is one record for Sheep River, Alberta, 7/2/1969.
There are a few pics on BugGuide. One which Martin Hauser thought was Eristalis rupium and another which he has yet to look at. The black pterostigma 3.5 times as long as broad is unique to Eristalis rupium in related species. And then there are black antennae and the obviously hairy eyes. I have emailed this picture to Martin Hauser who is away at the moment and hope he can find time to look at it.
Bill.
