A small white butterfly with obvious male and female dimorphism. The back of the body is dark brown and the belly is white. The back of the male butterfly's wings has a yellow background, and the top of the forewings is dark brown with orange stripes inside. There is a small dark brown spot at the end of the middle chamber. There is a row of dark brown spots along the outer edge of the hind wings, which expands into a broad dark brown band during high temperature periods. The background color of the ventral surface of the wings is yellow, and there are dark brown fine lines and small lines on the front half of the forewings and the wing surfaces of the hind wings. The dark brown markings on the back of the female butterfly's wings are similar to those of the male butterfly, but the other parts are white. The stripes on the ventral wings are similar to those of male butterflies, but the outer sides of the hind wings and forewings are yellowish white, and the rest of the wings are white.
