Well, it is Syrphus, but it's not going to be possible to ID to species from the photo. You will need to see the colour of the hind femora and the presence or not of hairs on the eyes. Even then it is not possible to split male S ribesii and S recta. Sad

Conopid is of course right to be cautious, but it's such a superb shot, maybe we could go a little further...
A sharp picture like this would be likely to show a fuzz, or halo, of eye-hairs in a male torvus - these really do look bare. To my eye, torvus often look darker on the abdomen, with more black and narrower yellow bands. Which leaves vitripennis, rectus and ribesii. Although vitripennis and rectus males are indistinguishable on present knowledge, is there perhaps enough yellow showing on the hind femur (more than a third of its length) to indicate ribesii? It's hard, because of the long hairs on the side of the abdomen, to be sure, but a call of "probable ribesii" seems reasonable to me.
Such sharply focused wings even had me looking for microtrichia on the basal cells - but with a photograph that would certainly be going too far!
Please submit more great shots like this Simon.
Happy hunting,
John

I would say that is zonaria but like you I'm just an amateur! I'm sure one of the regulars will be along to confirm (or not!) soon... Wink
