Notes:
Nationally scarce, in sand-dunes and on shingle beaches, along the coasts of England, Wales and eastern Scotland, also inland on the heaths of Hampshire and Surrey. In Hampshire, very local along the south coast, Hayling Island being the best-known locality, but there have been no recent record of the small, dark form from the heaths of north-east Hampshire. Not recorded on the Isle of Wight to date. Wingspan 38-44mm. The main confusion species is Cabbage Moth Mamestra brassicae, in which the reniform stigma is outlined white; in S. albicolon the reniform stigma is indicated by a pair of vertically opposed whitish dots on the distal margin of the dorsal half (MBGBI Vol 9). Larva feeds on Sea Rocket, Common Restharrow, Sea Sandwort, Sand Spurrey and Ribwort Plantain, over-wintering as a pupa.
