Orthetrum triangulare[2] is an Asian freshwater dragonfly species.[1] The common name for this species is blue-tailed forest hawk.[3][1][4][5][6] Two subspecies of Orthetrum triangulare are currently recognised, the nominate subspecies and O. t. malaccense.[1]
It is a medium-sized dragonfly with dark face and bluish eyes. Its thorax is also black with a broad apple green stripe on both sides. Segments 1-2 and 8–10 in the abdomen are black and the remaining segments are pruinosed with azure blue. It is usually found in marshes associated with hill streams where it breeds.[7][8]
