Giant Swallowtail Butterfly | Papilio cresphontes PUPAE
Papilio cresphontes, commonly known as the Giant Swallowtail, is one of the largest and most striking butterflies native to North America. Its wingspan ranges from 10-15 cm, making it an impressive sight in gardens, woodlands, and citrus groves. The butterfly is easily recognized by its striking black wings adorned with yellow bands and a distinctive "swallowtail" extension on the hindwings.
The underside of its wings is a lighter yellow-brown with similar patterns, allowing it to blend into its environment when resting. Caterpillars of this species resemble bird droppings, a helpful camouflage adaptation that deters predators. They primarily feed on plants in the citrus family, such as orange and lemon trees, which has occasionally labeled them as pests in commercial citrus orchards.
Adult Giant Swallowtails are important pollinators, sipping nectar from a variety of flowers, including lantana, phlox, and milkweed. Their graceful flight and vivid coloration make them a favorite among butterfly enthusiasts and a common sight in butterfly exhibits. The species is widespread, ranging from southern Canada to South America.
