A very rare species in Belgium.
The adults have only been observed in May. They fly during the day in bright sunshine around the top of the trees and later occasionally come to light.
The larva lives in the seeds of Acer campestre where it spins a cocoon to hibernate from September. Pupation in a cocoon under bark at the base of the host tree.
