A new butterfly species, Euthalia zubeengargi, has recently been discovered in the biodiverse forests of Arunachal Pradesh. This discovery has gained national attention not only for its scientific importance but also because the species has been named after renowned Assamese singer Zubeen Garg, highlighting the intersection of science and cultural recognition.

Common name: “Basar Duke”, inspired by a local Arunachal Pradesh police constable.
Habitat and Distribution: The butterfly was recorded in semi-evergreen forests at elevations ranging between 600 and 750 metres in the Leparada district.

Biology and Characteristics

The species belongs to the genus Euthalia, which is widely distributed across South and Southeast Asia.
- Members of this genus are typically associated with dense forest ecosystems.
The butterfly is characterised by: Earthy brown wings, Pale spot markings, typical of the genus.

Physical Characteristics

The butterfly is distinguished by:

Olive-brown wings with white markings
A subtle iridescent sheen
Unique wing patterns and anatomical features

These traits helped scientists confirm it as a new and distinct species.

Discovery and Location

The species was discovered in the Basar region of Leparada district in Arunachal Pradesh during field surveys conducted in 2025.

Discovered by Roshan Upadhaya and Kalesh Sadasivan
Found in semi-evergreen forests at elevations of 600–700 meters
Only two individuals have been recorded so far, indicating rarity

The butterfly has been given the common name “Basar Duke.”

Habitat and Behaviour
