Physocephala rufipes
Thick-headed Flies belong to the Canopidae family, but certain anatomical features, suggest that they are closely related to hoverflies. Several species are excellent wasp mimics and the larvae of this parasitic family feed internally in bees and wasps. The adults are nectar feeders, regularly visiting flowers. These P. rufipes were found and photographed near Walesby on 25/07/06 (lower photographs) and Sherwood Forest CP in July 2011.
