Have spotted this bug on a large daisy like flower, apparently collecting pollen like the dozens of other bees around it. Wasps seem to have distinct stripes rather than blocks of yellow on the abdomen and this one has longitudinal stripes on its thorax. it is around 2cm long but doesn't seem to be hairy like the other bees I've seen. With apologies for the quality of the picture - can you identify it for me. Many thanks
From the shape of the head I think it's a hover fly. Looking at online pics, this one seems most like it:

Here's the Wikipedia article http://en.wikipedia.org/wiki/Helophilus_pendulus
As it is raining (as usual) here is a small key to the five British species of Helophilus:
- Median stripe of face black ... 2
The key was (more or less) stolen from Tore R. Nielsen (Fauna Norvegica 1997:2 p.116). The rest was "stolen" from the web.
