It hibernates as a small larva and pupates in a tough cocoon, formed on a twig or branch of the food plant. The adults are active from dusk onwards and later come to light and sugar.
The adults fly from early June to mid-August in one generation a year. When conditions are right, small numbers can be observed until late in October.
The larva lives on lichens growing on the bark of deciduous and pine trees.
