March 16 , 2026 14 hrs 0 min 24 0
  • Scientists released India’s first comprehensive checklist of fireflies, identifying 92 species across 27 genera from records between 1881–2025.
  • Over 60% of the species are endemic to India, and many species have not been recorded again since the 1800s.
  • The Western Ghats have the highest diversity of fireflies, followed by North East India and the Gangetic Plain.
  • Fireflies belong to the beetle family Lampyridae and produce light through bioluminescence.
  • The light is produced by a chemical reaction involving luciferin, luciferase, oxygen, and adenosine triphosphate (ATP).
  • Fireflies are declining due to light pollution and urbanisation, highlighting the need for conservation.
