An extremely rare, local and declining species in Belgium. Nowadays only known from one location in LI.
On the brink of extinction.
The adults fly in one generation a year; from early June till late August. They are active by day and later come to light.
The larva feeds on various grasses and herbaceous plants like Corynephorus canescens, Festuca, Erica tetralix, Calluna vulgaris and Vaccinium. Hibernates as a small larva and pupates later in a flimsy cocoon among grass or heathers.
