Description and habitat

It is a dragonfly of medium size, coloured metallic green, sparingly marked with yellow. Its labium and labrum are bright yellow. Its lower part of frons and its sides are brighter yellow, changing to bright orange above and then brilliant metallic emerald-green. Its eyes are emerald-green when aged. Its pro-thorax is dark brown with a mid-dorsal yellow spot and thorax is dark metallic green, marked with yellow on the sides only. Its wings are hyaline with pterostigma dark brown. Its abdomen is glossy black with a metallic dark green reflex on dorsum, especially of the proximal segments, and marked laterally in bright ochreous color. Its anal appendages are black.[5][6]

Female is closely similar to the male. The larvae breed in montane lakes or in deep still pools of mountain streams.[5]

A survey jointly conducted by the Periyar Tiger Conservation Foundation, Indian Dragonfly Society and the Forest and Wildlife Department in Periyar National Park on October, 2017 found Hemicordulia asiatica. This was a rediscovery after 80 years of Fraser's initial sighting of this species from the Western Ghats.[7][8]

gollark: This is why my "design language" mostly has buttons with small margins, 1px borders, and no roundedness.
gollark: It's like notches - you theoretically have a bunch of area in the box/screen, but can't use it properly because a bit is cut off.
gollark: I feel like rounded corners mostly just waste space.
gollark: Also excessive margins.
gollark: Yes, space-wasting, there are useless rounded corners, an excessively large send button, and that sort of thing.
