Ischnura heterosticta, one of at least two species with the common name common bluetail, is a common Australian damselfly of the family Coenagrionidae. It is the largest of the six Ischnura species in Australia.[1] They are generally found near slow-running or still water.[2] The species is also salt tolerant.[3] It flies from October to March.[1]

The common bluetail is a small damselfly. Most males have blue eyes, a blue thorax, and a blue ringed tail. The females have a variety of forms including green, brown, black, and a form with very similar colourings to the male.[1][4]


In Australia, it is found throughout the entire continent including Tasmania.[5]
