Penhale sands near Perranporth on Cornwall's North coast is one of the last strongholds for this species in the county. The colony here also holds a high percentage of the rare aberration " taras" and what would appear to be intermediate forms these forms have more extensive white markings on the upper forewing giving it a quite striking appearance in comparison to the nominate form. This rare and very attractive aberration only occurres at a handful of sites in Britain so we are fortunate indeed to be able to find them here in our county.
