hairy wasp Dolichovespula sp? (sylvestris?)

This large, pale yellow and black striped wasp is covered in white or pale blond hair. Its large size and long antennae seem to indicate that it is a male. The facial and rear thorax markings look like those of the Tree Wasp, Dolichovespula sylvestris but the colouring and hairiness are strange.

On the wall of my house in south-eastern England. The yellow is much lighter than most vespula/dolichvespula species.

The shaggy hair and long antennae are reminiscent of Highland Cattle.
