The larva, or caterpillar, resembles a bird dropping when very young, but once more mature they become dark green. The front end of the caterpillar is rather swollen looking and has a pair of eyespots with black pupils. Just behind the eyespots are four purple dots running down the length of the body. During the day the caterpillar hides inside of a curled up leaf that it formed by drawing the edges of the leaf together with silk. The larvae generally feed at night. The caterpillar is roughly two inches in length at maturity.
The chrysalis is generally 1¼ inches in length, bumpy, pointed at each end, with the front end sporting a small pair of horns. The chrysalis is attached to a branch or twig vertically with a silken thread around the midsection. If the caterpillar pupates late in the year it will over-winter inside of its chrysalis and not emerge until spring. The winter chrysalis is brown mottled with dark brown and the summer chrysalis is mottled green. In Florida there are usually three broods, the first brood being the emerging butterfly from the overwintering chrysalis.
