Atrophaneura philoxenus" Gray

The Common Windmill Atrophaneura polyeuctes is the commonest member in India of the Windmills group of Atrophaneura, comprising tailed black swallowtail butterflies with white spots and red submarginal crescents.

Accordingly it has been dealt with in more detail than the other windmills.

Contents

[edit] Range

Northern India, Nepal, Bhutan, Myanmar, northern Thailand, Laos, Vietnam, southern China (including Yunnan) and Taiwan.

In India, the Himalayas from Kashmir to Sikkim, Assam, Arunachal Pradesh onto northern Myanmar.

[edit] Status

Overall, the butterfly is not rare. It is common in parts of Sikkim but becomes rarer westwards. It is extremely scarce in Shimla though not rare from Kangra west to Jammu and Kashmir.

[edit] Description

  • Length 110 to 140mm.
  • Sexes alike.
  • Black and white above with prominent swallowtail.
  • Red bodied. Tail has a red tip.
  • FW completely black above and below.
  • HW crenulated deeply twice on each side of swallowtail. Large oblong white discal spot in 5 (both UP and UN) and sometimes in 4. UPH has irregular marginal red crescents in 1a, 2 and 3 and a small white spot in 4.

[edit] Taxonomy

  • Atrophaneura philoxenus" Gray is considered a synonym.
  • A species Atrophaneura lama (Oberthür), described from western China, is regarded as a subspecies of A. polyeuctes by some.

[edit] Subspecies

It has five subspecies, two of which occur in India :-

[edit] Related Species

  • The three common species of windmills can be recognised by the differences in shape, number and location of white spots.
  • Rose Windmill, Atrophaneura latreillei, has a white discal band in 2, 3, 4 beyond the cell which is clearly trifurcated by black veins. A slightly smaller butterfly, the Rose Windmill has rose coloured lunules.
  • Great Windmill, Atrophaneura dasarada, has a number of two white spots in 4, 5 on UPH and three spots on 4, 5 and 6 on UNH. It is a slightly larger butterfly with broader swallowtail.

[edit] Habitat

This butterfly prefers forests and woods. Frequents river valleys. It occurs at low elevations (1000 to 5000 feet) in North East India but is found at higher altitudes in the western extent of its range - up to 11,000 feet in Kashmir.

[edit] Habits

This butterfly has a leisurely flight high above, but is easily recognisable by the thin long fore and hindwings. It is attracted to flowers and visits Clemanthe, Buddleia, Lantana and Rhododendron blossoms.

It is mimicked by a day flying moth Epicopa (or Epicopia) polydorus, which flies at the same period and over the same range as the Common Windmill and has much the same manner and habits.

[edit] Life Cycle

Has several broods where it finds suitable climate. Seen on the wing between April and September. The imago has a foul odour.
