The mature caterpillar resembles bird droppings to deter predators, if that doesn’t work they use their red osmeterium. Older instars take on the appearance of a small snake with a fake head and eyes. The coloration is dingy brown and or olive with white patches and small patches of purple. Fruit farmers often call the caterpillars orange dogs or orange puppies because of the devastation they can cause on their crops.

Giant Swallowtail Butterfly Range and habitat
P. cresphontes is mostly seen in deciduous forest and citrus orchards where they are considered major pest. They fly between May and August where there are 2 broods in the North and 3 in the south. They can range from southern California, Arizona as deep south as Mexico north into southeastern Canada. Giant Swallowtail Butterfly Life cycle
Adult females lay their eggs singly on the surface of the host plant, this egg is bright orange and darken with time. The caterpillars then eat and grow to about 2 inches before changing into a chrysalis. The chrysalis stage is variable but usually takes approximately 10-12 days, although in the fall they may stay in the chrysalis stage over winter and emerge in the spring.
