Queen common wasps (Vespula vulgaris) have been around for a few weeks now. I never see them feeding, just sunbathing, flying about the apple or cherry, but not appearing interested in the flowers, or searching for a suitable nest site. Today this one found our hedgehog house (hedgehogs, still snubbing this lovely house, better hurry up before wasps finish it off). The wasp started chewing at the old wood. Wasps make their nests out of saliva mixed with chewed pulp, which becomes pretty much paper mache and this queen is now building up hers.
