A rare species throughout Belgium.
The adults fly from mid May till late August in one generation a year. They are active by night and later come to light.
The larva lives mainly on Calluna vulgaris but also on a variety of deciduous trees, shrubs and herbaceous plants like Salix, Betula, Crataegus, Cytisus and Rubus. Hibernates as a small larva in a silk shelter attached to the food plant, often with several larvae together.
