November Moth Epirrita dilutata
([Denis & Schiffermüller], 1775)
Wingspan 38-44 mm.
Three of the members of the genus Epirrita, (November Moth, E. dilutata, Autumnal Moth, E. autumnata, and Pale November Moth, E. chrystyi), can be very difficult to separate on markings alone, especially as some show marked melanism. This species appears to be the most widespread and common, however, occurring over most of Britain.
The adults fly from late September to November, occurring in a wide range of habitats.
The larvae feed in late spring on a variety of trees and shrubs.
