Resident. Occurs sparingly at light in both vice-counties. Double-brooded flying mainly from mid June to mid August, and again from mid October to the third week of December, after an unusually active and intermittent hibernation, adults then fly most frequently of all from late January to late March. Larvae feed on silver birch and sweet chestnut. (Pratt, 2011).
