Dasysyrphus albostriatus
The direction and shape of the yellow bars on the abdominal segments (tergites) make this a relatively easy species to identify. I found two of these on Penny Pasture Common, where this picture was taken on 29/07/06. D. albostiatus is typically an insect of woodland edges, and is widespread through much of the UK.
