Adults are mainly dark green and black and are relatively slender and small compared to most aeshnids ( Fig. 68 ); they are crepuscular, sometimes flying at treetop level just before dark. Small, temporary, rainforest pools and tree holes are the preferred habitat. References are Williamson (1923a) and von Ellenrieder & Garrison (2003) . Triacanthagyna caribbea Williamson, 1923 . Publ.
