A fairly common species throughout Belgium.
The adults fly from May till July. They are active at dusk and later come to light.
The larva, when young, lives in a slight web on the underside of a leaf of Carpinus. 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 species has also been observed on Betula and Castanea.
