New Species - Hoverfly, Heliophilus pendulus

I actually took this picture in August 2013 when a hoverfly presented itself whilst I was photographing butterflies. However I had not a hope of identifying it from my generalist insect books once I found out that we have 281, yes 281, species of hoverfly in the UK. This ID is the first fruit of my recent purchase of the excellent 'Britain's Hoverflies' by Stuart Ball and Roger Morris that has a brilliant set of annotated photographs.
