Myathropa florea

Hoverfly, Myathropa florea, female, on Hogweed, Heracleum sphondylium, on the Orchid Bank
at High Elms Country Park, 14 July 2011.

I saw these attractive hoverflies several times last year, from April right through to October. Their bright golden fur makes them stand out, and the bat-shaped outline on the thorax, which you can see in the second photo, is distinctive.
