Hoverfly approx. 10-12mm long
No interactions present.
Probably, but could be Helophilus hybridus
It's a male (eye margins parallel atop the head), so the presence of a dark bar across the end of tergite 2 means it is not hybridus, and the abdominal colours are wrong for trivittatus. It has to be pendulus, then.

That's brilliant.Is there a book on hover flies that would tell you all that? 'Insects of Britain and Western Europe' has hardly any of the flies in the garden, let alone in detail.
British Hoverflies, by Stubbs and Falk is the main book. Out of print, I think, but you'd pick one up somewhere second-hand. I think it is due for an updated version before long.
Otherwise, there is a Wildguide to the commoner species coming out soon, which should be excellent...
Agreed. Stubbs and Falk "British Hoverflies" is excellent, with a key and great photos.
Thank you very much.
