A fairly common species in the Kempen, elsewhere in Belgium rare.
In the early stage the larva lives on the buds and later on the leaves of his host plant. Hibernates as an egg, laid in small batches on twigs of the food plant. Pupates underground in a cocoon. The adults come to light and sugar.
The adults fly in one generation a year; from late August till end October.
