June to August. Wales, Scotland, Ireland and northern England. Medium-sized dark-grey banded moth of mountains and moorlands, usually around exposed rocks. Generally found near heathers or bilberry.

This moth varies in colour from light to dark grey, but the darker central band bordered by white is distinctive.  It is similar to the Yellow-ringed Carpet but without the golden-orange scales along the central band of the forewing.  The Striped Twin-spot Carpet bears some resemblance, but is smaller in size and markings are not as bold.

The adults rest during the day on rocks, walls and tree trunks from which they are easily disturbed. they fly from dusk and into the night. The caterpillars can be found from July or Augusst to late the following May or June. They pupate in a cocoon among the stems of the foodplant.
