Davey, P., 2009: A species found widely across Britain, the larva feeding nocturnally on the blades of various grasses, especially those of tufted hair-grass (Deschampsia cespitosa). In Dorset, the moth is widespread and at low density. It is frequent in damp woodland and in the vicinity of river valleys, fens and marshes where reed-canary grass (Phalaris arundinacea) is the suspected foodplant of choice. It is rare in dry habitat such as heathland and grassland. Records from localities such as St Albans Head and Lyscombe Hill plus regular garden records from Poole suggest common couch (Elytrigia repens) and cock's-foot (Dactylis glomerata) as potential host plants. The moth is single brooded in June and July in the UK, but in Dorset the main generation occurs between late-May and early July, and a partial second brood has been noted from late July and into August in roughly half of the past twenty-five years.
