What is the discovery?

• A new species Euthalia zubeengargi (common name: Basar Duke) recorded in Leparada district, Arunachal Pradesh.
• Discovered during 2025 field surveys in semi-evergreen forests (600–750 m altitude).
• Research spearheaded by Roshan Upadhaya (RIMT University) and Kalesh Sadasivan (Travancore Natural History Society).
• Published in Entomon journal (Association for Advancement of Entomology).

Key Features & Ecology

• Belongs to genus Euthalia (widely distributed in South and Southeast Asia).
• Distinct earthy brown wings with pale markings.
• Habitat: Cool, shaded forest interiors with dense, moist undergrowth.
• Behaviour:
  • Feeds on tree sap and minerals from damp soil and Streams.

This discovery brings the total number of Euthalia species recorded in the NE region of India to over 80.

Key Takeaways

• Named species = scientific recognition + cultural tribute.
• Northeast India = high endemism and unexplored diversity.
• Conservation of forest microhabitats is crucial.
