Interesting Facts about Papilio xuthus:
Papilio xuthus is native to China, Taiwan, Korea, Japan, and the Hawaiian Islands. Like monarchs this species migrates seasonally. The caterpillars mimic bird droppings, giving them a leg up over other species of butterflies and moths that are easier targets for predators.
Swallowtail butterflies are large, colorful butterflies that inhabit every continent in the world except for Antarctica. Most are tropical species and there are over 550 different species included in this group.
We have several species of swallowtail here in the United States, and many states have adopted swallowtails as their state butterfly. Papilio machaon oregonius in Oregon, Papilio glaucus in Virginia, Georgia, Delaware, and South Carolina, and Papilio polyxenes in Oklahoma.
Swallowtails have tails on the end of their hindwings, which help them escape predators in the wild. In the hopes that a bird will grab onto their tail, which they don’t need in order to fly, instead of some other part of their wing or body which are more critical for survival, the butterfly has a chance to get away unharmed. The bird “swallows the tail” instead of the butterfly, hence the name “swallowtail”.
