Southern Bird Wing (Male)

The Southern Birdwing (Troides minos) is a large and striking Swallowtail butterfly endemic to Peninsular India. With a wingspan of 140–190 mm, it is the largest butterfly found in southern India.

It was earlier considered a subspecies of the Common Birdwing (Troides helena) but is now recognised as a valid species. (https://en.wikipedia.org/wiki/Troides_minos)

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.
