It is around 40~54-millimeter-long when spreading its wings. Its patterns vary greatly. Males (up) have black patterns on a yellow ground and females (down) have lemon yellow patterns on a dark brown ground. Females have well-developed dark brown color on the upper side of the wings, so it looks like yellow band on a black ground at first glance.

The butterflies emerge four to six times a year and usually inhabit near fields and paddies, grass in hills, or along rivers or streams. Females lay 20 to 120 eggs at one spot, on the underside of stem or leaves of food plants. The spots the eggs are developed to pupae vary including the underside of leaves or stem of food plants, surrounding trees or rocks. Their food plants is aristolochiaceae and they survive winter as pupae.
