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.
