Resident. The moth usually occurs singly, occasionally sparingly at mv light, in pine plantations and on heathland. Widespread in West Sussex but much less so in the eastern vice-county. Single-brooded, flying mainly from mid May to the second week of September, occasionally to early October. Larvae feed on pine elsewhere. (Pratt, 2011).
