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. 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. Until recently, Austroaeschna pinheyi was considered to be a subspecies of Austroaeschna unicornis.

GBIF citizen-science records
It is estimated from how often the Unicorn Darner is recorded against all the insects logged in Springbrook National Park (34 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
