The larva feeds on various grasses and herbaceous plants like Corynephorus canescens, Erica tetralix, Calluna vulgaris and Vaccinium. Hibernates as a small larva and pupates later in a flimsy cocoon among grass or heathers.

The adults fly in one generation a year; from early June till early September. They come to light.
