Large butterfly. The wingspan of the male is up to 95 mm, the female is up to 110 mm ^[3] . The main background of the upper side of the wings is pinkish-gray. Wings with wide pale brown margins. A light brown wide stripe runs along the outer edge of the wing. The marginal border on the front wings is cut by a white wavy band, which is surrounded by a double dark line curving in its upper third, arcuately curved to the rear edge of the median cell. It approaches almost perpendicular to the trailing edge of the wing. Each wing has a relatively large ocular spot ^[2] . On the front and hind wings they are wide-rounded, reddish-brown, centered by a narrow transverse black stroke. On the hind wings, the ocular spots are rounded, much larger than on the hind wings, with a narrow white crescent semicircle on the inside. Sexual dimorphism is weakly expressed: females are larger than males, antennae of males are comb-shaped ^[2] .
