Scientific name: Dyscia fagaria

May to August. England, Scotland, Ireland and north Wales. Occurs on heathland, moorland, bogs and raised mosses. A medium grey moth with two dark cross-lines on the forewing. Usually found near Heather, Bell Heather and Cross-leaved Heath.

The colour of the wings varies with habitat.  Moths in upland areas tend to be whiter and those from heaths and bogs are grey or even brownish.  The male is larger and generally paler than the female, but the two dark lines across the forewings separated by a dark dot are diagnostic of this species.

The adult males can easily be found basking on stones and bare ground including burned areas during the day. The caterpillars can be found from July to the following May.
