Davey, P., 2009: A local and decreasing species confined to southern Britain, the larva feeding on oak (Quercus spp.). In Dorset, the moth is very local and chiefly restricted to old oak woods in the north and north-east of the county, often occurring in the vicinity of the largest oaks in the wood. Managing a varied age structure of oak in Piddles Wood, Holt Forest, Boys Wood and Castle Hill Wood would be beneficial to maintaining existing colonies of this species.
