Giant Swallowtail Caterpillar Care & Facts

The giant swallowtail butterfly caterpillar, also known as the Papilio cresphontes, is a fascinating species that can be found in gardens across the northern regions of the United States. Unlike monarch butterflies, which rely on milkweed as their host plant, the giant swallowtail caterpillar can be found on a variety of host plants, including common rue, wafer ash, and northern prickly ash. The eggs of the giant swallowtail are easy to find, as they are deposited on the surface of green leaves and have an orange-peel color. The caterpillars go through several stages of growth, resembling bird droppings and even snakes to deter predators. When threatened, they can release a pungent odor from their red horns. As the caterpillars grow, their appetites increase, but they are not as ravenous as monarch caterpillars. Eventually, they will form a chrysalis, which is the third stage of their life cycle. After a period of time, the chrysalis will transform into a beautiful giant swallowtail butterfly.

Giant Swallowtail Butterfly Caterpillar Life Cycle

The life cycle of the giant swallowtail butterfly caterpillar consists of several stages. It starts with the eggs, which hatch after about 4 to 10 days. The caterpillar then goes through five instars, or periods between molts, during which it undergoes significant changes in appearance.

“The younger instars resemble bird droppings, while the more mature instars resemble small snakeheads.”

The caterpillar also has a red, antenna-like structure called an osmeterium, which emits a pungent odor when the caterpillar feels threatened.

After three to four weeks, the caterpillar will pupate and form a chrysalis. The chrysalis hangs at an angle with its top suspended from silken threads. After a period of time, the adult butterfly emerges from the chrysalis to start the cycle again.
