Distribution
Imago
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.
