The wings are brown on the front, with 7-8 translucent white spots on the forewings, arranged in a semi-ring shape; there are 4 white transparent spots on the center of the hind wings, arranged in a straight line. The back of the wings is light in color with yellow powder, and the markings are similar to those on the front of the wings. The size of the two spots at the middle chamber end of the male butterfly is basically the same, while the upper one of the female butterfly grows larger, and the lower one degenerates into a small dot or disappears.
