Davey, P., 2009: A species occurring in southern Britain, but absent from the Midlands, the larva feeding on lichens and mosses growing on the stems and branches of trees. In Dorset, the moth is common in deciduous woodland and scrub, frequent on heathland containing derelict heather (Calluna vulgaris and Erica spp.) where its foodplants abound, and rare in dry, open habitat. The national norm is for a single brood in late June to early August. Many examples seen in September and even October, suggest a partial second brood in most years.
