Diacamma indicum

Diacamma indicum, also known as Indian queenless ant, is a species of ant of the subfamily Ponerinae. It is found from India, Sri Lanka, and Bangladesh.
Distribution and Nesting
This species thrives in a variety of habitats and displays remarkable nesting flexibility. Colonies inhabit simple, mostly subterranean nests consisting of a single chamber and entrance, often accompanied by a secondary tunnel. During monsoon seasons, these ants construct elevated nest mounds, raising the nest entrance by an average of 3.4 cm and narrowing the opening to reduce water intrusion.
