Two generations from May to mid-July and late July to early September. Common to England and Wales, less frequent in Scotland and Ireland. Named after the grey spectacle shaped marking which can be seen on the thorax when viewed from the front.

Flies from dusk and regularly comes to light. The thorax is covered in fur which is piled up into a turret. The markings vary little with a dark blackish central band which contains an oval and kidney shaped marking.

The adult feeds on flowers including the Red Valerian (Centranthus ruber) and cultivated Sage. They overwinter as pupae.
