Used to be a very rare species around the millenium, nowadays (since about 2010) a fairly common and widespread species in Belgium.
Native
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 till 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.
