Discovery of Euthalia zubeengargi in Arunachal Pradesh
A newly identified butterfly species has been recorded in the Leparada district of Arunachal Pradesh, named Euthalia zubeengargi. This fresh find pays homage to Zubeen Garg, a celebrated cultural icon from Assam, whose demise in September 2025 resonated deeply with fans across the region.
Research Team and Common Name Proposal
The butterfly was discovered by a dedicated team of researchers comprising Roshan Upadhaya, a scholar from Punjab’s RIMT University, and Kalesh Sadasivan from the Travancore Natural History Society. They have suggested the common name ‘Basar Duke’ for this new species, reflecting the local cultural significance.
Field Observations and Findings
The team’s observations took place during field surveys conducted throughout 2025 in semi-evergreen forests at elevations ranging from 600 to 750 meters. Their findings, published in the latest issue of *Entomon*, a quarterly journal by the Association for Advancement of Entomology, detail a rare instance of only two male specimens being documented—one collected and one photographed in its natural habitat.
Distinct Characteristics of Euthalia zubeengargi
Euthalia zubeengargi belongs to the genus Euthalia, which is widely distributed across South and Southeast Asia. This group is well known for its earthy brown wings adorned with delicate pale spots. Upadhaya noted that the new species can be distinguished by its unique wing patterns and structural features, confirming its status as a separate species.
Habitat and Behavior
Field observations indicated that Euthalia zubeengargi thrives in the cooler, shaded interiors of forests. The butterfly was primarily spotted resting on low vegetation, sipping tree sap, and occasionally sourcing minerals from moist surfaces near streams. Its activity peaks mainly from late morning to early afternoon, characterized by short, leisurely flights from one plant to another.
Conservation Concerns and Future Studies
The researchers highlighted the crucial role of dense and moist forest undergrowth in the species’ survival. However, despite their efforts, much about the butterfly’s life cycle, including its breeding patterns and preferred host plants, remains elusive. Euthalia zubeengargi is now one of over 80 butterfly species cataloged within this genus throughout India’s northeastern region, prompting further exploration and study in this rich biodiversity hotspot.
Conclusion
The discovery of Euthalia zubeengargi reflects the ongoing need for conservation and research of butterfly species in India, particularly in the biodiverse landscapes of Arunachal Pradesh. This new addition not only underscores the importance of preserving natural habitats but also celebrates the legacy of influential figures like Zubeen Garg.
