Some more pictures from different angles would be useful to estimate colour and hair pattern of the femora, lateral and frontal view of the head, etc. From the key http://web.archiv...stkey.html you see which characters have necessarily to be visible.
This female has a square pterostigma, so either E. interrupta or E. jugorum. The latter usually has a dark zig-zag pattern on the wings, but it may be faint. Compare thread http://www.dipter...;pid=50661.
The locality should always been given, it might be helpful!
Regards, Sundew

P.S. Please use the Syrphidae forum for hoverfly questions.

So it should be E. interrupta. E. jugorum is absent from Britain.
