A new study has found that overexploitation of 25 species of host plants valued for their medicinal properties has affected swallowtail butterflies in forests on the Brahmaputra’s northern bank.

About Swallowtail butterflies:

  • These are a group of butterflies in the family Papilionidae (order Lepidoptera). 
  • Appearance: They are named for the characteristic tail-like extensions of the hindwings, although many species are tailless. 
  • Distribution: The swallowtail butterflies (Papilio) are found worldwide except in the Arctic. 
  • India hosts 77 of the 573 swallowtail butterfly species recorded across the world so far.
  • Many swallowtails mimic the coloration and patterns of butterflies that are protected by bad taste.
  • Threats: Illegal cattle farming within the protected areas, agriculture and tea cultivation near the habitats, illegal tree felling and pesticide use are among the crucial factors contributing to the decline in the number of these Swallowtail butterflies.
  • Ecological Importance of Butterflies: These are valuable indicators of the environment, whose health can influence their presence, abundance, and diversity.
