Males and females are sexually dimorphic, meaning that they look very different from each other.
   Females are more colorful and can be found in a variety of colour morphs.The female's coloring can range from mostly black with red spots to forewings that are primarily white with black edging and veins. The hindwings are black with red spots and sometimes have a large, central white patch.
   The male's forewings are black with faint white lines along the outer edges. The hindwings are solid black towards the body and lined with white towards the outer edges. Each hindwing has a small cluster of red spots on the lower inside edge.
