62.0280 (B&F: 1454)
Suspected resident and immigrant. Usually occurs singly or sparingly at mv light, although it is occasionally fairly common amongst plantations of evergreens, on heathland, and along parts of the coast when apparently migrating. Probably generally distributed across much of the county. Single-brooded, flying mainly from late May to mid September, occasionally to late September. Larvae feed on "Scotch fir" (Scots pine).
