Drone fly;

Female. Syrphidae, Diptera. Nice case of batesian mimetism. It looks like a bumblebee but it is a fly, without sting. The yellow band separating the eyes indicate it is a female. The black marks in teh middle of the wings is distinctive of Volucella elegans.
The female deposits the eggs in bumblebees and social bees nests where the larvae will feed on the hive residues. Adults feed on flowers nectar, as the one in the picture.
