Davey, P., 2009: A local species in southern Britain, the larva feeding on decomposing plant material and refuse. In Dorset, the moth occurs widely, but usually is only observed as singletons in deciduous woodland, on farms, on thatched buildings and in sea cliff localities where nesting birds are frequent, such as at Durlston.

Immigration may account for some of the records, but the widespread nature of the moth across the county makes research difficult. The national norm is for a single brood in July and August, but in Dorset, a bivoltine cycle is evident with a small partial second brood in October.
