Davey, P., 2009: A species found widely across much of England and Wales, but more local in Scotland, the larva feeding on birch (Betula spp.) and occasionally alder (Alnus spp.). In Dorset, the moth is local, at low density, and, with one exception, associated with mature birch woodland. The exception is Powerstock Common where the dominant tree is alder, and probably hosts the insect. The moth is roughly twice as numerous as the Brindled White-spot1950, a species that it is often seen with at light traps.
