Davey, P., 2009: A species of large reedbeds in southern Britain, the larva feeding in the stems and rootstocks of common reed (Phragmitis australis) and reed sweet-grass (Glyceria maxima), and the adult is on the wing during June and July. In Dorset, the moth is mostly restricted to large reedbeds and their environs in the Poole Basin from Wareham to Christchurch where it is locally common, but it is occasionally recorded elsewhere.
