A common species throughout Belgium. The most widespread and commonest of the three Epirrita species.
Although some sources claim that you can identify the 3 Epirrita species by the markings on the front wing, this is only a guide and there is much overlapping and therefore not certain. If you want to be 100% certain, then examination of the genitalia is necessary. This only applies to males, the female genitals are too variable to identify.
The adults fly from late September till November. They are attracted to light and occasionally to sugar.
The larva lives on a variety of trees and shrubs. Hibernates as an egg, laid near buds on twigs.
