The common Mormon (Papilio polytes) is a common species of swallowtail butterfly widely distributed across Asia.
This butterfly is known for the mimicry displayed by the numerous forms of its females which mimic inedible red-bodied swallowtails, such as the common rose and the crimson rose.
The male has one morph only. It is a dark-coloured swallow-tailed butterfly. The upper forewing has a series of white spots decreasing in size towards the apex. The upper hindwing has a complete discal band of elongated white spots. It may or may not have marginal red crescents. The males are generally smaller in size than the females but not always. Both male and all forms of the female of P. polytes can vary considerably in size depending on climatic region.
The female of the common Mormon is polymorphic. In South Asia, it has three forms or morphs.
