The female lays her eggs singly. They are laid on the leaves, stems, and flowers of the host plant (the host plant is the plant that the caterpillar feeds on). The egg is pale green. The caterpillar is banded with yellow and black. There are three pairs of black body extensions. The first pair is near the head. The second pair is on the thorax. The third pair is near the end of the body. The chrysalis is green. It has gold spots. There is a black and gold band on the abdomen. It is very similar to the Monarch's chrysalis. It has three or more broods (a brood is a group of offspring) per year.
