Norfolk status Rare immigrant, with a breeding population in Scotland.
Adult moths fly at night and males come to light, but not females, which are rarely encountered. The larvae feed in the autumn on various pine species, but predominantly Scots Pine, overwintering in forest litter, continuing to feed in the spring until July. When pine is unavailable they feed on Norway Spruce, Larch and other conifers. Reputedly a serious pest of forestry trees.
Historic Norfolk records Curtis writes - Joseph Sparshall, Esq., took a fine male in the Norfolk and Norwich hospital, 23rd July 1809. Barrett writes - If this is correct, it is almost certain that the specimen must have been imported in the pupa state with foreign timber... I think it likely that Mr Sparshall mixed his foreign and British insects, and thus fell into various errors. (Trans. N&NNS 1874)
