A new butterfly species, Euthalia zubeengargi, has been recorded from Arunachal Pradesh, adding to India’s rich biodiversity, particularly in the Northeast.

About Euthalia zubeengargi

Euthalia zubeengargi is a butterfly species belonging to the genus Euthalia, which is widely distributed across South and Southeast Asia. The discovery highlights the ecological richness of Arunachal Pradesh, a known biodiversity hotspot.

• Habitat: Found in semi-evergreen forests at elevations of about 600–750 metres, particularly in cool and shaded interiors.
• Distribution: Part of a genus with 80 species recorded in Northeast India, indicating high regional diversity.

Physical and Behavioural Features

Members of the Euthalia genus, including this species, are typically associated with forest ecosystems and exhibit:

• Appearance:

• Earthy brown wings with pale spots
• Camouflaged coloration suited for forest habitats

• Behaviour:

• Prefer low vegetation and shaded areas
• Feed on:
  • Tree sap
  • Minerals from damp surfaces near streams
• Show activity mainly during late morning to early afternoon
• Characterised by short, slow flights between nearby plants

Ecological Significance

• Butterflies like Euthalia zubeengargi serve as important bioindicators:
• Their presence, diversity, and population reflect the health of ecosystems
• Sensitive to environmental changes such as:

o          Habitat loss

o          Climate change

o          Pollution

Thus, their discovery aids in monitoring biodiversity and conservation status of forest ecosystems.
