Davey, P., 2009: A species occurring in all districts apart from northern Scotland, the larva feeding on blackthorn (Prunus spinosa), hawthorn (Crataegus spp.), apple (Malus spp.), bramble (Rubus fruticosus) and pear (Pyrus communis). The snowy-white ground colour of the moth plus its roof-like posture when at rest gives the impression of a bird dropping. The vernacular name comes from the pattern made by the group of silvery scales on the branched wing rays in the centre of the forewing. In Dorset, the moth is common where blackthorn abounds, at low density where hawthorn is dominant, and rarely seen in habitats where blackthorn and hawthorn are absent. The peak of the second brood is on average, twice as large as that of the first.
