  • A new species of dung beetle has been discovered in Tawang district of Arunachal Pradesh.


  • The species, Enoplotrupes tawangensis, is shining dark blue in colour and, measuring up to 27 mm, is relatively bigger than most of the dung beetles.
  • Dung beetles belong to the super family scarabaeoidea, having clubbed antennae and pro- tibiae (pro-legs) modified for burrowing dung inside the soil.
  • This group of insects are considered beneficial to the environment as they help in nutrient cycling of the soil. Often referred to as little recyclers, these scavenger beetles require mammalian dung to survive. “Insects comprise almost 65% of all animal species on the planet. From India, approximately 65,000 species of insects are known, of them, more than 22,000 species are beetles.
  • Dung beetles are the one of the fascinating group of insects because of their ability to bury dung deep in the soil and are indicators of the ecological health of an ecosystem,”
  • Other than the relatively large size and distinct blue colour, another important distinguishing characteristic of this species is the strong sexual dimorphism, with the fronto-clypeal horn shorter in females than males.
