Davey, P., 2009: A local species in central and south-east England, and south-east Wales, the larva feeding nocturnally on common reed (Phragmites australis) and hiding by day in old hollow reed stems. In Dorset, the moth is frequent to common in coastal fens at Abbotsbury, Radipole and Lodmoor, and around the harbours at Poole and at Christchurch. Small colonies also occur in fens on the River Piddle and the River Frome near Wareham. Dispersal accounts for examples trapped some distance from known core habitat.
