In India, the larvae are reported to occur in streams and other running waters; they can also be found in tea and coffee plantations, but only at the forest edge.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): There is continuing loss of the habitat of this species largely caused by the conversion of land for agricultural use (including the drainage of wetlands) and the development of mining. Agrochemical pollution is also a threat.

Conservation Actions [top]

Conservation Actions: It is present in many protected areas in Sri Lanka, and might occur in Kudremukh National Park in Karnataka, India. It is protected by national legislation in India.
