Davey, P., 2009: A local species over much of Britain, but absent from northern Scotland, the larva feeding on sallow (Salix spp.), aspen (Populus tremula) and bilberry (Vaccinium myrtillus). In Dorset, this wonderfully-patterned moth is widespread, occurring most frequently in sallow-rich deciduous woodland, but it tends to be at very low density with no more than singletons seen on any given night. The following individual was trapped on the coast at a time of immigration: Portland Bird Observatory, at MV light on 10 July 1995 (M Cade).
