Foodplant and Larval Feeding Signs
Betula spp. including B. pendula (silver birch) and Corylus avellana (hazel) - see plant distribution map for hazel. In Europe also recorded on Alnus glutinosa (alder), Carpinus betulus (hornbeam) and Populus tremula (aspen).
The larva spins a shoot or rolls a leaf.
Finding the Moth
Larva: the spun shoots and rolled leaves can be found from late April to early July.
Adult: can be disturbed from trees during the day, flies at night and comes readily to light.
The long thin shape of the moth and the distinctive dark costal triangle on a pale background make this a distinctive species.
From mid-July to early October.
