Could be or could be E arbustorum. Need to see if it has a face stripe. Note: E nemorum now known as E interruptus.

Reading Stubbs, I would incline towards
E interruptus, as he says the orange spots on T2 in females are always well separated from the hind margin, unlike
E arbustorum. My experience in Essex is that the arbustorums flying now will be almost gilded in appearance in flight, the way
Epistrophe eligans looks, and it is only later, in the autumn that they are dark with the narrow cream banding.

More reading of Stubbs - can you check the tip of the mid tibia? - if entirely pale, it is presumably
E abusivus, but this species is apparently more common at the coast where there is marshland. In this photo the vital area is just enough obscured by the body on both sides so one cannot be certain - how frustrating:@

Ahh, thanks Susan (& Nigel) - but that was the only decent pic I got of it so no view of the tibia - sorry :( Never mind - I know it's a bit of a long shot to identify something from a photo :)
