A very rare and local species in Belgium, known from the Kempen and the south.
Hibernates as pupa in a cocoon low near the ground.
The adults fly from mid April till mid May. They come to light, usually late at night.
The larva lives mainly on Vaccinium myrtillus, but also on Salix and other deciduous trees.
