Assam butterfly diversity documentation

The documentation of butterfly diversity in the BTR provides useful context for biodiversity conservation and ecological corridor studies in Northeast India, though it is not a major policy or legislative event that would be asked directly.

Notes

  • The Assam Forest Department released a booklet documenting butterfly diversity in the Bodoland Territorial Region (BTR).
  • The BTR forest landscape covers 3,653 sq. km. and consists of tropical evergreen, semi-evergreen, moist mixed-deciduous forests, and alluvial grasslands.
  • The region serves as a confluence point for the Indo-Malayan and Indo-Gangetic biogeographic zones.
  • BTR hosts 346 of Assam’s 620 recorded butterfly species, making it one of the richest butterfly habitats in Northeast India.
  • It is the only ecological corridor in the Northeast where butterfly species from the Eastern Himalayas, Indo-Malayan region, and Indo-Gangetic plains coexist.
  • Rare and endemic species recorded include the yellow-crested spangle (Papilio elephenor) and Swinhoe’s flat (Celaenorrhinus zea).
  • The landscape supports cultural heritage, such as the Bodo community's 'Bagurumba' dance, which is inspired by butterfly mud-puddling behavior.

Part of a longer story

This is day 1 of 3 in Butterfly diversity documentation in Assam, which has been running since 5 July 2026. Reading it whole is usually worth more than reading today alone — the exam asks how something developed.
