Davey, P., 2009: A common species over England and Wales, less frequent further north, the larva feeding on broad-bladed grass species such as common reed (Phragmites australis), cock's-foot (Dactylis glomerata) and reed canary grass (Phalaris arundinacea). The nocturnal- feeding caterpillar can be found characteristically in-situ on the stem of its foodplant during the day. In Dorset, the moth is widespread and common, but rises to abundant in reedbeds, inland marshes, river and stream valleys, and the moister woods. It is locally abundant on coastal grassland on chalky soil, notably on Portland, St Alban's Head and Durlston, and in this drier biotype the foodplant is likely to be tor-grass (Brachypodium pinnatum).
