  • 29 May 2026

In May 2026, citizen scientists reported the rediscovery of the rare dragonfly species Gynacantha khasiaca, commonly known as the Long-tailed Duskhawker, from the Namdapha National Park and Tiger Reserve in Arunachal Pradesh.

  • The species was last scientifically described in 1914 from the erstwhile Abor Hills, making this a significant rediscovery after more than 110 years.
  • It is a large dragonfly characterized by pale brown and green colouration and crepuscular (active during dawn and dusk) behaviour.
  • The species possesses two large compound eyes containing thousands of tiny lenses (ommatidia), providing an almost 360-degree field of vision.
  • It is capable of hovering motionlessly in the air and rapidly patrolling territories.
