Researchers from the Ashoka Trust for Research in Ecology and the Environment (ATREE) have discovered two new species of solitary bees in Arunachal Pradesh. The species, which belong to the genera Elaphropoda and Habropoda, have been named Elaphropoda triangulata, after the triangle-shaped markings on its abdomen, and Habropoda adi, after the Adi indigenous community of Arunachal Pradesh, which inhabits the region where the bees were collected.
