Two-tailed Swallowtail (Papilio multicaudata)

Caterpillar

The two tailed swallowtail larva has mottled black and white coloration all over the body that makes them look somewhat like bird droppings (which is an adaptation to camouflage). As they mature, they begin to turn orange-brown or bright green with distinctive eyespot markings close to the thorax area, behind the head. This often helps them fool or confuse predators and enemies.

The chrysalis of the two tailed swallowtail is gray-brown in color and remains hidden in some protective location that helps them camouflage well with the background.

Each of the four wings shows four, nearly parallel stripes, with the outermost stripe being the shortest. At the end of each secondary wing, there is a curved row of patches in purplish blue, below which, there are a few spots or bars in orange.
