Genus/SpeciesIschnura aurora (Brauer, 1865)
AbundanceVery common
DistributionFound throughout Australia from alpine areas to the arid inland. They are known to disperse widelely by being blown along with storms.
HabitatThese inhabit a wide range of still water, including swamps and temporary pools, and can also be found by sluggish river water.
DescriptionThese are small damselflies (about 25mm long) of which the mature males have green, red and blue markings (as well as the obligatory black). The females have black all along the top of the abdomen (tail) and otherwise have significant green markings.

Similar Species
Like many other species in this genus, Ischnura aurora feature two pale spots behind the eyes (these are blue in mature individuals).
Female Ischnura heterosticta, while significantly larger, are overall very similar in appearance (when viewing photographs). A couple of segments near the end of the abdomen are however pale on the upper side whereas these are dark for I. aurora.
BehaviourThese mostly perch horizontally on the side or on top of emergent aquatic vegetation, low to the water surface. Females deposit eggs in to such vegetation (or other soft material) by submerging their tails.
ObservationsMales are aggressive hunters of females and will grab newly emerged females (as seen in this image).
