Similar species:
Forewing: 6 to 9mm
Habitats: Woodland and hedgerows with trees.
Habits: The moth flies high around the trees during the evening. It later comes to light.
Foodplant: The larva feeds in a nut of Beech, hollowing it out and filling it with frass. When the Beech mast falls in autumn, the larva leaves and spins a cocoon in the leaf litter, where it overwinters (sometimes twice). It pupates in a dense cocoon, in the leaf litter, amongst moss, under bark or under rotten wood.
