See comments under November Moth

The distribution map for this species is misleading as it is a map of where moth recorders have examined specimens as per page 101 of the field guide! It is quite a lot more common than records suggest, especially in birch woodland where it can sometimes be the commonest of the genus. It is much less common in gardens where the vast majority will be November Moth. Do not rely on the forewing markings. Unless you have examined the underside of the tip of the abdomen, you should log the moth as "November Moth aggregate".

Sutton & Beaumont, 1989: There are very few confirmed records for this species but when genitalia preparations were made of similar 'November Moths' taken at Pannal, Harrogate (VC64), forty-three per cent were found to be this species. All these would have been counted as E. dilutata (Denis & Schiffermuller) without this special attention so it is likely that it is quite common in the County. Dunn and Parrack (1986) believe it is probably more western in distribution than the other Epirrita species in Northumberland and Durham but whether this will prove to be the case in Yorkshire is not clear as yet.
