of the Lepidoptera of Belgium

Furcula bicuspis (Borkhausen, 1790)

A not so common and local species throughout Belgium. Always in small numbers.

The larva lives on Betula, sometimes also on Alnus. Hibernates as a pupa in a solid cocoon attached to the bark of the food plant.

The adults fly in one, probably two generations a year; from late April onwards to mid August. They come to light.
