The autumnal moth (Epirrita autumnata) is a moth of the family Geometridae. The species was first described by Moritz Balthasar Borkhausen in 1794. 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 Sápmi (Lapland), in some years, the numerous autumnal moth larvae defoliate square miles of birch forests on mountains.[1]

Description
editThis species is very similar to the November moth, the small Autumnal moth, and the pale November moth, and identification is usually only possible by examining the genitalia.[2] In general, this is the least variable of the four, with melanic forms occurring less often. It is also usually on the wing earlier in the year, flying in September and October,[1] although the flight seasons of all three species overlap.
The caterpillar feeds on a wide variety of trees and shrubs.[3][4] The species overwinters as an egg.
