Troides minos Cramer, 1779 |
Troides minos, the southern birdwing, is a large and striking Swallowtail butterfly endemic to Peninsular India. With a wingspan of 140–190 mm, it is the largest butterfly of India.
It was earlier considered a subspecies of the common birdwing (Troides helena) but is now recognised as a valid species.
The species is more common in the Western Ghats, which is a biodiversity hotspot with a high degree of endemism in many taxa. It is much sought after by collectors and is a highlight of many butterfly tours in the Western Ghats. It is the state butterfly of Karnataka, India.
Description from Charles Thomas Bingham (1907) The Fauna of British India, Including Ceylon and Burma, Butterflies. Volume II.
Male and female. Differs from Troides helena cerberus as follows.
Western Ghats and parts of the Eastern Ghats.
The butterfly is locally very common in the southern and central Western Ghats. Also found in southern Maharashtra and northern Goa where it is uncommon. Despite its restricted range and endemicity, the butterfly is not known to be threatened but the IUCN recommends continuous monitoring.
Found up to 3,000 feet (910 m) in the Western Ghats. Found in diverse habitats from low-land evergreen forests near the coast to mixed deciduous forests, dry scrub and agricultural fields.
Active during early morning hours when both sexes feed in the forest on Lantana and diverse food plants. Later on, it is seen sailing as high as 30 to 40 feet (9.1 to 12.2 m) over the countryside until it descends later in the evening to feed again. It flies in a leisurely manner circling around jungle clearings and also frequents hill tops. A determined flier, it is known to cover very large distances before settling. The only food source is nectar, it also visits gardens and orchards and sips from domestic plants such as Mussaenda, Ixora and Lantana.
