Aralam Butterfly Sanctuary

June 29, 2025

The Kerala State Wildlife Board recently renamed the Aralam Wildlife Sanctuary in Kannur as the Aralam Butterfly Sanctuary, thereby becoming India's first protected forest dedicated entirely to butterflies.

About Aralam Butterfly Sanctuary:

  • It is located in the Kannur District of Kerala.
  • It is spread over 55 sq. km. area of forests on the Western Ghats.
  • The Cheenkannipuzha River forms the main drainage system of Aralam.
  • Vegetation: Tropical and semi-evergreen forests.
  • It is home to over 266 species of butterflies, accounting for more than 80 percent of all butterflies in Kerala. Some of these are unique to this region, while others are endangered.
  • Between October and February, the sanctuary transforms into a living rainbow when butterflies migrate here from the lower slopes of the Western Ghats.
  • An amazing scene is created during this season, also known as the time for the Common albatross butterfly, when hundreds of butterflies fill the air and fly amid tall trees, orchids, and wildflowers.
  • Every January or February, the sanctuary holds a Butterfly Migration Study, which celebrates this seasonal movement and deepens our understanding of these pollinators.
  • In addition to butterflies, Aralam is home to several animals, including elephants, giant squirrels, leopards, and a variety of birds.
