The Pellucid or Large Pied Hoverfly is one of the largest UK hoverflies, looking a little like a bumblebee and very fast-flying. With its white band round the body and black spots on the wings it is quite a striking insect. The adults feed on nectar from flowers, but lay their eggs in the underground nests of social wasps, like the Common or German Wasp. On hatching the larvae drop to the bottom of the wasps nest where they live on dead insects and unhatched wasp larvae, emerging as adults the following summer.
