Elattoneura tetrica

Elattoneura tetrica, the black and yellow bambootail, is a damselfly species in the family Platycnemididae. It is endemic to Western Ghats in India.

Description and habitat
It is a medium sized damselfly with black-capped pale blue eyes beneath, marked with a black equatorial belt. Its thorax is metallic velvet-black on dorsum. The anterior border of mesepimeron and the lower part of sides are creamy white, separated with a broad stripe in black. The lower part may get pruinosed. Its abdomen is black, pruinosed on the basal segments in adults. Segments 3 to 6 have thin baso-dorsal bluish-white annules. Anal appendages are black.

Female is similar to the male; but paler eyes and dull colored thotax. Teneral males look like the female in colour and markings; adult lose almost all their markings due to pruinescence.

It is closely associated with submontane streams and lakes where it breeds.
