Arunachal Pradesh: Kaiser-e-Hind Butterfly sighted in Mechuka

“The presence of this rare and beautiful butterfly has the potential to attract many butterfly tourists to Shi-Yomi district and Mechuka in particular,” said Dr Joram Khopey, Deputy Director of the State Blood Transfusion Council at the Directorate of Health Services, who along with his friends spotted this butterfly species on May 22 last.

“The median altitude of Mechuka is around 7000 ft above sea level. It is felt that if proper survey is carried out by experts many more high-altitude butterflies could be sighted. The vegetation and altitude of Mechuka seems suitable especially for Bhutan Glory, another beautiful and rare butterfly,” he said.

Kaiser-e-Hind is much sought after by butterfly lovers and enthusiasts for its beauty and rarity. Moreover, its presence is a sign of rich biodiversity especially of plants and trees (Magnolia sp. tree is the host plant for Kaiser-e-Hind butterfly).

The butterfly with its shimmering greens, bright yellows and delicate blacks is a treat to the eyes. The green iridescence of the wings has been found to be due to three-dimensional photonic structure of the scales and is the subject of much research, Dr Khopey said.

Kaiser-e-Hind (Teinopalpus imperialis), which literally means “Emperor of India”, is a rare species of swallowtail butterfly found in small pockets of Nepal, Bhutan and along the Eastern Himalayas in India, including Arunachal Pradesh, West Bengal, Meghalaya, Assam, Sikkim and Manipur. In these areas, it occurs at medium and higher elevations from 6000 to 10,000 feet above sea level in well covered forest terrains. It is also found in Northern Myanmar, Northern Vietnam and in the Sichuan Province of China.

In Arunachal Pradesh, till now Kaiser-e-Hind butterfly has been found in Talle Valley and surrounding areas in Ziro, Lower Subansiri district, Eaglenest Wildlife Sanctuary in West Kameng district and Luyor Pass area in Siang district.

It is noteworthy to mention that there was a proposal to name Kaiser-e-Hind butterfly as the State butterfly of Arunachal Pradesh during the Pakke Declaration (Pakke Tiger Reserve 2047 Declaration on Climate Change, Resilient and Responsive Arunachal Pradesh) in 2021.

“Sighting of this butterfly in Mechuka was astonishing, unexpected and a jubilant moment in the same breath. If proper surveys are made in areas with similar altitude & vegetation such as in Mishmi Hills, Anjaw district, Upper Subansiri district, Pakke-Kessang district, Namdapha Wildlife Sanctuary etc sighting of this butterfly is highly likely. If sighted in more areas, Kaiser-e-Hind butterfly can definitely be named as the State Butterfly of Arunachal Pradesh. By doing so, this rare butterfly can be protected, conserved better and saved from extinction from our state,” Dr Khopey said.

Kaiser-e-Hind butterfly is a protected species under Schedule II of Wildlife Protection Act 1972. Hence, its smuggling and unauthorized handling or killing is a punishable offence under the Act.
