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. Where detailed examination has not taken place records should be added as Epirrita dilutata agg.

Wide range of habitats.

The adults fly from late September to November.

The larvae feed in late spring on a variety of trees and shrubs.

Occurring commonly over most of Britain. In a recent survey to determine the status of all macro moths in Britain this species was classified as common.

As an aggregate group the November Moths are common in our area but records confirmed by genitalia examination are few, hence its scarce recorded status in VC55. L&R Moth Group status = C (very scarce resident or rare migrant, but genitalia examination needed for secure identification)
