Specimens in nature


The caterpillar lives in the female catkins, at first mining the flowers and the seeds. Later on it spins a tough web. The catkins are completely destroyed and then the larva moves to the buds which are hollowed out completely. Pupation in a narrow cocoon in a crack in the bark of the tree. The cocoon is very well camouflaged because it is covered with particles of lichen.
The adults are active at dusk and later come to light.
