About Chonala albistricta:
- Chonala albistricta, or Narrow-banded Wall, is a new species of butterfly.
- It was discovered at Mayodia Pass in the Lower Dibang Valley district of Arunachal Pradesh.
- It belongs to the genus Chonala, a small group of mountain butterflies found in high-elevation regions of the Himalayas and neighbouring parts of Asia.
- It is the tenth known species in the genus Chonala worldwide and only the second species from the genus recorded in India.
- The species has been named after the distinctly narrow, unevenly bent white band on its forewing.
- This high-altitude butterfly species is notoriously difficult to study as they occur in small populations, fly for only a brief period each year (June to August), and inhabit remote mountain passes that are often challenging to access.
- The species breeds only once a year.
