A rather common species throughout Belgium.
The larva lives in a pocket in a folded leaf or between two leaves neatly spun together on the food plant.
It overwinters full-fed in the last spinning, which falls to the ground. Pupation in the larval habitation.
The moths are active at sunset and later come to light.
The adults have been observed from the end of April till the end of August. It is not clear whether these late specimens are representing a partial second generation.
The larva lives mostly on Populus tremula, occasionally on P. nigra.
