Dark-barred Twin-spot Carpet
Xanthorhoe ferrugata

(Clerck, 1759) 1725 / 70.052

Norfolk status
Believed to be over-recorded in Norfolk.
Very similar to Red Twin-spot Carpet, which has a dark-barred form.

The notch on the inner edge of the cross-band, close to the costa, has proven to be an unreliable method to identify this species.

Red Twin-spot Carpet also has a dark-barred form, leading to confusion.
However a red-barred form of Dark-barred Twin-spot Carpet is apparently rare and should be treated as indistinguishable without dissection of the genitalia.

Using caution, only classic examples with solid black cross-bands should be assigned to this species without dissection of the genitalia.

Recorded in 65 (88%) of 74 10k Squares.
First Recorded in 1873.
Last Recorded in 2023.
