Davey, P., 2009: A local species in south-east Britain, the larva feeding nocturnally on common reed (Phragmites australis) and reed canary-grass (Phalaris arundinacea), and hiding by day in old hollow reed stems or amongst reed litter. In Dorset, the moth is frequent amongst common reed growing along the coast in shallow water, in brackish estuaries and on wet clay cliffs; it also colonises fens inland in the Poole Basin. Occasionally, dispersed singletons are observed some distance from reed habitat.
