The Southern Birdwing, also called the ‘Sahyadri Birdwing’, is a large and striking butterfly species found in South Asia, majorly in the Western Ghats. It is the second-largest butterfly in India. Even in mid-flight within the canopy, it stands out because of its exceptionally large size, with wings that exceed the dimensions of smaller birds. This notable wingspan is the reason behind its name, “birdwing.“

Males typically have black wings with greenish-blue markings, while females have a more extensive pattern with cream-coloured markings. Collectors eagerly seek the Southern Birdwing, considering it a prized find, and it often takes centre stage during butterfly tours in the Western Ghats. It is the state butterfly of Karnataka.
