A fairly common species throughout Belgium, especially in the northern part.
The larva lives in a folded leaf on the food plant. It eats out holes between the veins. Pupation in detritus on the ground. The adults fly at dusk and later come to light.
The adults fly usually from May towards September, occasionally later.
The larva feeds on Quercus species or, less often on Alnus glutinosa.
