Dihing Patkai National Park Documents 165 Butterfly Species

Guwahati: Dihing Patkai National Park is now a confirmed hub for rare insects. A recent biodiversity trail identified 165 distinct butterfly species across the rainforest. Researchers found 37 endangered species among the total count. Documentation efforts covered the Joypur, Lakhipathar, and Soraipung ranges, alongside Deomali in Arunachal Pradesh.

The fourth edition of the event ran from July 28 to 31, 2026. Experts, students, and conservationists combed the area to track the insects. Total records for the park now top 260 species when including historical survey sites. Assam Chief Minister Himanta Biswa Sarma highlighted the data on social media. "With 165 butterfly species recorded, including 37 endangered species, Dhing Patkai stands as a safe haven for Assam’s incredible biodiversity," he stated.

The park spans Dibrugarh and Tinsukia districts. It holds over 200 bird species and at least 200 butterfly types. The government officially designated the site as a national park in 2021. Previous studies in the Soraipung range identified 92 species, with 13 under Wildlife Protection Act schedules and 11 unique to the Eastern Himalayas. These ongoing counts inform wider forest conservation efforts.
