    The adult butterflies have a wing span of about 4 cms. The upper surfaces of the wings are orange with dark brown markings, and an eyespot on each wing. The males have an extra dark line running from near the middle of each forewing to the middle of the inner margin. This sex-brand appears silver in some angles of the lighting.
