Ischnura heterosticta, one of at least two species with the common name common bluetail , ^[3] is an Australian damselfly of the family Coenagrionidae. ^[4] It is the largest of the three Ischnura species in Australia. ^[5] They are generally found near slow-running or still water. ^[6] The species is also salt tolerant. ^[7] It flies from October to March. ^[5]
