The Tasmanian darner (Austroaeschna tasmanica), is a species of dragonfly in the family Aeshnidae, which includes some of the world's largest dragonflies. It is found in Tasmania, Australia. The species was first described by Robert Tillyard in 1916 and inhabits streams and rivers. Also referred to as "hawkers", the name "darner" derives from the fact that the female abdomens look like a sewing needle, as they cut into plant stem when they lay their eggs through the ovipositor.
