Papilio polites ranges widely from Sri Lanka
and India to Indo-China, S. Japan, the Philippines and Sunda Islands in SE
Asia. Its caterpillars feed on a variety of Rutaceae plants (Citrus and
allied genera, including lemon and orange plants) and the butterfly is
palatable to its predators such as birds. Various female forms of this species
derive protection from such predators with their resemblance to distantly
related, chemically protected (toxic) red-bodied Swallowtails, which
experienced birds avoid eating. This type of resemblance is called Batesian
mimicry, which is restricted in P. polytes to females, and the toxic
species they resemble are called "models".
Non-mimetic (form cyrus) females look like males, whereas mimetic female morphs (forms stichius, polytes, romulus...) mimic distantly related, toxic Pachliopta swallowtails.
In Vietnam, two subspecies have been recorded : P. polytes polytes (Sino-Japanese taxon: N. Vietnam to Japan) and P. polytes romulus (Indomalayan taxon: C. and S. Vietnam, + Thailand, Malaisia, Laos, India...).

Male Papilio polytes
The Common Mormon can be found in both natural
and urban areas - cultivated Citrus has ensured this. Males and females can often be seen feeding at flowers. Males are also commonly found mud-puddling in lowland forests.In Vietnam, two subspecies have been recorded : P. polytes polytes (Sino-Japanese taxon: N. Vietnam to Japan) and P. polytes romulus (Indomalayan taxon: C. and S. Vietnam, + Thailand, Malaisia, Laos, India...).

Common Mormon courtship. Female (on the left) display the non-mimetic form cyrus
The courtship 'dance' of this species is
particularly beautiful. The male appears to mob the female, until she
eventually settles on a plant to forage on flowers, fluttering her wings. The male
hovers continuously around her, occasionally butting her. The female then takes off, flies upwards to a next flower with the male following, facing her at all times.

This Y-shaped eversible gland located mid-dorsally behind the head, is a universal characteristic of swallowtail caterpillars (Papilionidae).
