A rather rare species in Belgium mainly known from the southern provinces, but after 1980 slowly spread northwards and nowadays throughout the country.
The larva lives first between spun leaves on terminal shoots, and later feeding openly at night, hiding between spun leaves by day.
Hibernates as an egg, laid on the twigs of the food plant.
Pupates in leaf litter or just under the soil surface.
The adults come to light and sugar.
The adults fly in one generation a year from late June till late August.
The larva lives on Salix orPopulus tremula.
