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.

With luck
About 10% of wildlife watchers report a Southern Birdwing sighting in Bengaluru on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 182nd most-seen of the 477 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January–February and September–October
In those months about 10% of wildlife watchers report a Southern Birdwing in Bengaluru on a given day, against under 5% in March–August and November–December, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Southern Birdwing sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5
Of the 5 cities where we can rate Southern Birdwing sightings, Bengaluru ranks 5th at about 10%. The best odds are in Ponnani (India, about 20%), Thiruvananthapuram (India, about 20%) and Kochi (India, about 10%).
Same family: Papilionidae
The closest relatives of the Southern Birdwing that you can see in Bengaluru (family Papilionidae, Swallowtails and Parnassians) are Common Mormon Swallowtail (about 40%), Lime Swallowtail (about 30%) and Tailed Jay (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Birdwing is recorded against all the insects logged in Bengaluru (22 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.
