Davey, P., 2009: Widespread in Britain, occasionally reaching plague proportions on acid uplands, the larva feeding on hard-bladed grasses such as mat-grass (Nardus stricta), purple moor-grass (Molinia caerulea) and fescues (Festuca spp.). In Dorset, the moth is now seldom recorded. The few records suggest low-density colonies on short-turf chalky soil where sheep's fecscue (Festuca ovina) abounds, and on dry heaths where disturbance has created conditions suitable for fine-leaved sheep's fescue (Festuca filiformis).
