Local on roadside verges, rough ground, woodland edges and clearings, in western England and Wales. In Hampshire and on the Isle of Wight extremely rare, and only occasionally recorded: voucher specimens should be retained for confirmation of identification. Wingspan 17-20 mm. Very similar to
Grey Pug E. subfuscata, from which males are separated by slight differences in the antennae, and females only by dissection of the genitalia. Larva feeds on Common Ragwort and Goldenrod, over-wintering as a pupa.
