A fairly common species throughout Belgium.
Native
The larva, when young, lives in a slight web on the underside of a leaf. Later, it spins two leaves together. It overwinters in a cocoon spun in a partially cut and folded section of a leaf. Pupation takes place in the cocoon which falls from the tree in winter.
The adults are active at dusk and later come to light.
The adults fly usuallyfrom May till July with most observations during June.
The larva lives on Carpinus betulus. The species has also been observed on Betula and Castanea.
