Local on heathland and moorland throughout much of the British Isles. In Hampshire most frequent in the New Forest; there is one record from the Isle of Wight and a few from outside the New Forest, which suggest the species may, on occasion, adapt to cultivated heathers. Wingspan 14-20 mm. The narrow forewings with prominent apex, especially in the female, and the purplish brown and silver-white coloration are characteristic [Bradley]. Larva feeds on Heather and Bilberry, living between shoots spun together with silk.
