Nationally scarce (Nb) in woodland, downland and scrubland throughout much of southern England. In Hampshire locally common and exclusively on downland along the border between north and south Hampshire, on sites such as Stockbridge Down, Leckford, Porton Down, Magdalen Hill Down, Broughton Down and Micheldever Spoil Heaps. There have been no recent records from the Isle of Wight. Wingspan 13-18 mm. Readily distinguished from other species of Ancylis by the characteristic chestnut-brown forewing markings [Bradley]. Larva feeds on Buckthorn and Alder Buckthorn, living between leaves spun together with silk, over-wintering in a cocoon.
