Troides minos, the southern birdwing, also called Sahyadri birdwing, is a large and striking species of swallowtail butterfly. It is endemic to southern India. With a wingspan of 140–190 mm, it is the second largest butterfly of India. It is listed as Least Concern in the IUCN Red List.
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 of southern India, 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.

It is the 35th most-seen of the 76 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
August and November–December
In those months about 30% of wildlife watchers report a Southern Birdwing in Ponnani on a given day, against under 5% in January–April and September, the lowest months.

GBIF citizen-science records
It is estimated from how often the Southern Birdwing is recorded against all the insects logged in Ponnani (11 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
