Papilionidae (Swallowtail Butterflies)
These are large-sized butterflies. They are often black-and-yellow striped, or they are black with rows of yellow, blue, or red dots. The hindwings often have tails. Some species, such as the Battus philenor (Pipevine Swallowtail), are distasteful and toxic, while other species of swallowtail mimic this butterfly. The caterpillars tend to be smooth and green with markings from other colors. They have horn-like structures that appear when the caterpillar is disturbed, emitting a noxious smell. The caterpillars feed on a wide variety of plants, including members of the Carrot family, Wafer Ash and Prickly Ash, Spicebush and Sassafras, pipevines, wild cherries, and other trees. The pupae are angular-shaped, green or brown, and slung from a stem with a silk girdle.
