Austroaeschna unicornis is a species of dragonfly in the family Aeshnidae, known as the unicorn darner. It is found in eastern Australia, from Brisbane to Tasmania and around Adelaide in South Australia, where it inhabits rivers and streams.
Austroaeschna unicornis is a long-bodied, brown to black dragonfly with pale blue markings.
Etymology The genus name Austroaeschna combines the prefix austro- (from Latin auster, meaning “south wind”, hence “southern”) with Aeshna, a genus of dragonflies.
The species name unicornis is Latin for "one-horned", referring to a horn-like projection on the back of the female’s head.
