A local and very rare species in Belgium, more frequent in the south of Belgium.
Hibernates as an egg in a bark crevice on the food plant. Pupates in a silken cocoon spun between leaves or among leaf litter. The adults come to light and sugar.
The adults fly in one generation a year; from mid August till half of October, sometimes till early November, but most specimens were seen during September.
The larva lives mainly on Populus tremula, but also on other Populus species.
