The subfamily Papilioninae consists of about 550 species worldwide. These are divided into 4 tribes: Leptocircini, Papilionini, Teinopalpini and Troidini. The Troidini includes the Parides Cattlehearts of South America, the Ornithoptera Paradise Birdwings of Papua New Guinea, and the Trogonoptera and Troides Birdwings of tropical Asia, and Atrophaneura.
There are about 50 species in the genus Atrophaneura, most of which are confined to the Oriental region, although some extend their range to New Guinea which lies in the Australian region. Some workers split Atrophaneura into a number of smaller genera e.g. Pachliopta, Losaria, Balignina and Byasa. Consequently this species is listed as Byasa polyeuctes in some works.
The various members of the genus Atrophaneura are known as Windmills, Batwings, Club-tails and Roses. They all have elongated black forewings. In most species the hindwings have spatulate tails and are marked with red submarginal spots and/or white patches. Most also have red markings on the head, thorax and abdomen.
Atrophaneura are unpalateable to birds, and are mimicked in appearance by various edible species. Papilio polytes e.g. produces several different female forms, including romulus f. theseus which is a superb mimic of Atrophaneura aristolochiae. Insectivorous birds are unable to distinguish between mimic and model, and having had the unpleasant experience of tasting aristolochiae will reject the almost identical but perfectly edible polytes. For human observers distinguishing between the two species is easy though because polytes has an all-black head and body.
Atrophaneura polyeuctes is probably the commonest and most widespread member of the genus. It is found in India, Nepal, Burma, Thailand, Tibet, China and Taiwan.
