The autumnal moth (Epirrita autumnata) is a moth of the family Geometridae. It is found throughout the Palearctic region and the Near East and has a much wider distribution than its two close relatives (see below). In Lapland, in some years the numerous autumnal moth larvae may defoliate square miles of birch forests on mountains.
