Davey, P., 2009: A local species in Britain, the cannibalistic larva feeding nocturnally on various tree and shrub species, and on other caterpillars. In Dorset, the moth is common in old oak/birch woodland, frequent in deciduous woods and among scrub and at low density elsewhere. "It is one of the few moths that is partial to the blossom of sweet chestnut (Castanea sativa)." (W Parkinson Curtis manuscript).
