Guwahati: Independent researcher Sarangapani Neog has documented 281 butterfly species within Assam’s Hollongapar Gibbon Wildlife Sanctuary. His new book, the second edition of Butterflies of Gibbon Wildlife Sanctuary, covers findings from a 12-year project spanning 2012 to 2024. The sanctuary in Jorhat district covers 20.98 square kilometers. It remains a key habitat for the endangered western hoolock gibbon.
The 321-page guide uses high-resolution field photos to help readers identify butterflies through wing patterns, colors, and unique markings. Every species gets its own page with details on flight periods, behavior, and habitats. Neog designed the guide to be accessible for students, forest officials, and amateur naturalists. "The book is the culmination of years of documenting butterflies in their natural habitats," Neog stated.
Experts Isaac Kehimkar, Peter Smetacek, Purnendu Roy, Young James, and Saito Motoki reviewed the manuscript before its release. Assam Education Minister Ranoj Pegu led the formal book launch. Both Assam Governor Lakshman Prasad Acharya and Chief Minister Himanta Biswa Sarma endorsed the work as a gain for local conservation. The document now serves as a primary reference for future biodiversity monitoring in Northeast India.
