Very similar, but much more common than Dark-barred Twin-spot Carpet. (see next species for info)

Can be separated by the underside of the forewing, Dark-barred Twin-spot Carpet being uniform grey with little contrast. Red Twin-spot Carpet shows a contrasting pattern with deep ginger colouration towards the apex of the underside.

Red Twin-spot Carpet also has a dark banded form, leading to confusion with Dark-barred Twin-spot Carpet. Determination by dissection of the genitalia may be required.
