Nationally Scarce B

Resident and suspected immigrant. In danger of extinction in both vice-counties. In East Sussex the moth occurs singly at mv light, generally on heaths and in deciduous woods; undetected in West Sussex since 1992. Single- brooded, flying mainly from early July to mid August, occasionally from late June. The larval foodplant has yet to be determined in Sussex, although birch serves elsewhere. (Pratt, 2011).
