I'd recommend these site for hoverfly ID...
This one http://www.microscopy-uk.org.uk/mag/artmay07/cd-hoverflies.html shows how to tell sex, and this one helps ID which species (or genus as it is often hard to be sure about species without microscopic examination along with years of experience)...

Epistrophe

As well as the yellow on tergite 2 being wrong for Syrphus, the yellow bands on the abdomen are too broad at the margin for a Syrphus, really. The moustache bands of Syrphus are missing; the parallel bands are more typical of Epistrophe. It could be E. diaphana, but I do not think that yellow is pinched at the margin of the abdomen, as it is in that species.

Syrphini

You do need to check the yellow-and-black banded hoverflies quite carefully. Although the majority are going to be Syrphus of one species or another, there are one or two similar genera which can get overlooked, if you stop looking closely. The parallel bands on the abdomen of this fly are what alert you to it being something different.

Epistrophe

It would be useful if someone could add/change their agreement to Epistrophe, to correct the ID from a Syrphus sp.(assuming they agree!). Otherwise, it will keep appearing beneath identifications of Syrphus...though there may be no more of those before the spring, now, I suppose.
