Species Account


Sutton & Beaumont, 1989: Quite widely distributed but only occasionally common and distinctly rare in some areas. This species seems to take the place of C. vaccinii (Linnaeus) in open country.

2012 (CHF): Widespread across the county but with a more patchy distribution than Chestnut and in general it is less of a woodland moth. Common in the autumn but much less common than Chestnut in the spring and recorded in smaller numbers. These two species can on occasions be tricky to tell apart. Dark Chestnut has a more pointed forewing and a more shiny appearance. It is usually but not always darker and some borderline cases may be best left undetermined.
