Davey, P., 2009: A widespread species in southern Britain becoming more rare further north, the larva feeding nocturnally on various deciduous tree and shrub species; it is also cannibalistic. In Dorset, the moth is frequent in deciduous woodland, particularly in old oak woods, but becomes scarce in open, tree-less habitat. The larva may be found during the day in the crevices of oak trunks.
