The only overwintering stage of social wasps are queens. Males died at the end of the autumn after mating, and the workers a bit earlier. Their large paper nests are now empty, as the life cycle of social wasps lasts for less than one year. Queens overwinter in buildings or other dry places, but the strong wind and mild temperatures have probably helped stir this one out of her hiding place.
The 'anchor mark' on her face identifies her as a common wasp, Vespula vulgaris.
