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, but most specimens were seen during September.
The larva lives mainly on Populus tremula, but also on other Populus species.
