A fairly common species throughout Belgium, especially in the northern part.
The adults fly from late mid May till the end of August. They fly at dusk and later come to light.
The larva lives in a folded leaf of Quercus species or, less often, Alnus glutinosa. It eats out holes between the veins. Pupation in detritus on the ground.
