Discovery of New Butterfly Species in Arunachal Pradesh
In early 2024, researchers from the Zoological Survey of India (ZSI) documented a new butterfly species belonging to the Papilionidae family in Arunachal Pradesh. This species was named after the renowned singer Zubeen Garg, highlighting cultural integration in scientific nomenclature (The Hindu, 2024). Arunachal Pradesh, a northeastern state, hosts nearly 600 butterfly species, accounting for half of India's total butterfly diversity of over 1,200 species (ZSI, 2022). This discovery contributes to the growing inventory of endemic species in the region, emphasizing the state's ecological richness.

Biodiversity Significance of Arunachal Pradesh
Arunachal Pradesh covers approximately 7.5% of India's land area but harbors over 50% of the country's butterfly species (ZSI, 2022). Its forest cover stands at 79.33%, the highest among Indian states (Forest Survey of India, 2023). The region's varied topography and climatic conditions create microhabitats conducive to species diversification. However, shifting cultivation (jhum) and expanding infrastructure pose significant threats to butterfly habitats, causing fragmentation and population decline (MoEFCC, 2023).
- High endemism in butterflies reflects broader biodiversity richness.
- Butterflies serve as ecological indicators for habitat health.
- Habitat loss due to anthropogenic activities threatens species survival.
Legal Framework Governing Biodiversity Conservation
India’s constitutional and legal provisions mandate biodiversity protection. Article 48A directs the state to protect and improve the environment. The Biological Diversity Act, 2002 (Sections 6 and 18) regulates biodiversity conservation, sustainable use, and equitable benefit sharing. The Wildlife Protection Act, 1972 (amended 2006) offers legal protection to endangered species, though butterflies are generally protected under the Biodiversity Act unless specifically listed. The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006 recognizes community rights, affecting conservation in biodiversity-rich tribal areas. The National Biodiversity Authority (NBA), established under the Biological Diversity Act, oversees biodiversity management and regulation.
- Article 48A: Constitutional environmental directive.
- Biological Diversity Act: Governs documentation, access, and benefit sharing.
- Wildlife Protection Act: Species-specific protection, primarily for vertebrates.
- Forest Rights Act: Balances community rights with conservation imperatives.
- NBA: Regulatory and advisory authority on biodiversity issues.
Institutional Roles in Biodiversity Documentation and Conservation
The Zoological Survey of India (ZSI) conducts faunal surveys and species documentation, critical for identifying new species like the butterfly named after Zubeen. The Indian Council of Forestry Research and Education (ICFRE) researches forest biodiversity and promotes sustainable livelihoods such as butterfly farming. The Arunachal Pradesh Forest Department implements conservation policies locally. The Ministry of Environment, Forest and Climate Change (MoEFCC) formulates and enforces environmental laws, while the Wildlife Institute of India (WII) provides research and training in wildlife conservation.
- ZSI: Taxonomic research and species discovery.
- ICFRE: Biodiversity research and livelihood promotion.
- Arunachal Forest Dept: Ground-level conservation enforcement.
- MoEFCC: Policy and regulatory oversight.
- WII: Capacity building and scientific research.
Economic Dimensions of Biodiversity Conservation in Northeast India
The Union Budget 2023-24 allocated approximately ₹4,000 crore for environmental and biodiversity initiatives, reflecting increased fiscal prioritization (Union Budget, 2023-24). Northeast India contributes about 7-8% to India’s GDP but supports over 50% of the country’s butterfly species (ZSI, 2022). Ecotourism in Arunachal Pradesh has grown annually by 12% over the last five years, driven largely by biodiversity attractions (Ministry of Tourism, 2023). Butterfly farming and related eco-friendly livelihoods have the potential to generate ₹50-70 lakh annually in local economies (ICFRE, 2023), providing sustainable income sources while incentivizing habitat protection.
- Significant budgetary allocation for biodiversity conservation.
- High biodiversity concentration correlates with economic potential.
- Ecotourism growth linked to butterfly and general biodiversity appeal.
- Butterfly farming as a model for sustainable livelihoods.
Comparative Analysis: India and Costa Rica on Butterfly Conservation
| Aspect | India (Arunachal Pradesh) | Costa Rica |
|---|---|---|
| Biodiversity Status | 7.5% land area, >50% butterfly diversity of India | Global biodiversity hotspot with rich butterfly fauna |
| Conservation Strategy | Lacks comprehensive state-level butterfly strategy | Payment for Ecosystem Services (PES) programs implemented |
| Ecotourism Impact | 12% annual growth in Arunachal Pradesh | 25% increase in revenue due to PES-driven habitat conservation |
| Habitat Conservation Results | Threatened by shifting cultivation and infrastructure | 30% increase in butterfly habitat over a decade |
| Community Participation | Limited integration with conservation and livelihoods | Strong community involvement through PES incentives |
Critical Gaps in Arunachal Pradesh’s Butterfly Conservation
Despite rich biodiversity, Arunachal Pradesh lacks a dedicated, comprehensive butterfly conservation strategy that integrates community participation and sustainable livelihoods. This gap leads to underutilization of biodiversity for local economic development and insufficient habitat protection. Existing conservation efforts are fragmented and often do not align with tribal forest rights or local socio-economic realities, limiting effectiveness.
- Absence of state-level butterfly-specific conservation policy.
- Weak linkage between biodiversity conservation and tribal livelihoods.
- Inadequate habitat protection against shifting cultivation and infrastructure projects.
- Limited community engagement in biodiversity management.
Significance and Way Forward
- Systematic biodiversity documentation, exemplified by the new species discovery, is essential for informed conservation planning.
- Integrating biodiversity laws (Biological Diversity Act, Wildlife Protection Act) with tribal rights under the Forest Rights Act is necessary for balanced conservation.
- State-level butterfly conservation strategy should be developed, incorporating community participation and sustainable livelihood models such as butterfly farming.
- Adopting Payment for Ecosystem Services (PES) schemes, inspired by Costa Rica, can incentivize habitat conservation and boost ecotourism revenue.
- Strengthening institutional coordination among ZSI, NBA, ICFRE, MoEFCC, and state forest departments will improve policy implementation.
- It provides for the establishment of the National Biodiversity Authority (NBA).
- It offers legal protection to all endangered species including butterflies under Schedule I.
- It mandates equitable sharing of benefits arising from the use of biological resources.
Which of the above statements is/are correct?
- It grants individual and community forest rights to tribal and forest dwelling communities.
- It exempts forest rights areas from all environmental regulations.
- It impacts biodiversity conservation by recognizing community roles in forest management.

What is the significance of naming the new butterfly species after Zubeen Garg?
The naming of the new butterfly species after Zubeen Garg, a prominent cultural figure, symbolizes the integration of local cultural identity with scientific discovery, enhancing public awareness and pride in regional biodiversity (The Hindu, 2024).
Which legal Act governs the equitable sharing of benefits arising from the use of biological resources in India?
The Biological Diversity Act, 2002 governs equitable benefit sharing from biological resources, ensuring that local communities and stakeholders receive fair compensation (Sections 6 and 18).
What percentage of India’s butterfly species is found in Arunachal Pradesh?
Arunachal Pradesh hosts approximately 600 butterfly species, which is about 50% of India’s total butterfly diversity of over 1,200 species (ZSI, 2022).
How does the Scheduled Tribes and Other Traditional Forest Dwellers Act, 2006, affect biodiversity conservation?
