The Tasmanian Darner (Austroaeschna tasmanica) is an Australian species of dragonfly in the Aeshnidae family, which includes some of the largest of the dragonflies on the planet. 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.Photo: JJ Harrison
