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