See November Moth agg.
Sutton & Beaumont, 1989: As with E. christyi (Allen) the true status of this moth in Yorkshire is difficult to ascertain due to confusion with other members of the genus. However, three of the moths examined at Pannal (see E. christyi) were of the present species (six percent of the similar moths captured) and there is another record which has definitely been confirmed by genitalia examination. It has not been stated whether any of the records below which do not contain a comment have been checked in this way.
2012 (CHF): This species is usually better marked than November and Pale November Moths and typical specimens usually turn out to be this species. It is safer however to dissect them as it is very easy to make mistakes. It appears to be widespread in small numbers all across the county.
