Hello Jezlee,
it seems to be a male Syrphus species. Difficult to say if it is S. ribesii or S. vitripennis since the hind femur is not well visible.

French regards,
chlorophana.

Certainly Syrphus, but I wonder whether it might not be S. torvus - the close-up of the eyes suggests that there may be eye hairs - but I'd not like to bet on it

The eyes seemed bare to me, but it is not obvious it's true. Wink
Roger, I've got your book "Hoverflies of Surrey". It's very interesting for the ecology descriptions (visited flowers, flight times...) and the photograps of the plates are beautyfull.

French regards,

Hello Chlorophania

If you look at the eye behind the antenna there seem to be indications of hairs but the clarity is not sufficient to be certain - however, these sorts of angles do highlight hairs that may be pretty obscure, although in S. torvus I would normally expect males to be reasonably hairy eyed.

Just goes to show photos can only be used to a certainf degree, and on the whole I avoid giving definite IDs for Syrphus.

Thanks for kind words about the book - seems like a very long while ago!

Regards

Roger
