Davey, P., 2009: A species found in southern Britain, the larva feeding on blackthorn (Prunus spinosa), hawthorn (Crataegus spp.), buckthorn (Rhamnus cathartica), sallow (Salix spp.), wild plum (Prunus domestica), and apple (Malus spp.). This is the largest of the 'Eggars', the caterpillar measure up to 90mm long when fully grown. In Dorset, the moth is thinly scattered and at low density, but not uncommon where hawthorn and blackthorn predominate. The Lappet, like the Pale Eggar1632 and the Small Eggar1633, appears to have become less frequent in recent years, and changes in the management plus the removal of scrub and hedgerow habitat on chalky soils undoubtedly accounts for the decline of all three species. Chamberlaynes: "A female emerged from pupa, taken as a larva at Tincelton, in late afternoon of 13 July 1935 and was left in a cage in my bedroom. The unfortunate male had been attracted in and was found fluttering in a slop-pail the next morning. The male was put outside, however, the same male reappeared inside after dark, but this time was found in a jug of milk" (H Andrewes).
