Austroagrion cyane, the south-western billabongfly, is a species of damselfly of the family Coenagrionidae. Despite their common name, they have been found not only in south-western Australia, but also in diverse locations across Australia.
Habit & Habitat Austroagrion cyane are permanent residents of aquatic habitats. They prefer slow-moving water. Adults grow to around 20-30 mm in length. Females are less common than males and are mostly attracted to ephemeral swamps.
Etymology The genus name Austroagrion combines the prefix austro- (from Latin auster, meaning "south wind", hence "southern") with Agrion, a genus name derived from Greek ἄγριος (agrios, "wild"). Austroagrion thus refers to a southern representative of that group.
The species name cyane is derived from Greek κυανῆ (kyanē, "dark blue"), referring to its distinctive blue colouring.
