Orchard Swallowtail Butterfly

Unlike most of the members of the family Papilionidae, orchard swallowtail butterflies lack tails on their hind wings. In the larval stage, orchard swallowtails voraciously chew the leaves of economically important orange, tangerine, and lemon trees. The caterpillars are such noisy feeders that their leaf crunching sounds can be used to locate them at night.
