The Green Darner is one of the largest and fastest-flying of living dragonflies, able to reach speeds of 53 mph (85 km/h). Evidence of prehistoric dragonflies of much greater size exists among fossils that date to the era of the dinosaurs.
This species has several nicknames, including "Darning Needle" for its speed, "Mosquito Hawk" for its predatory habits that help to eliminate a common insect pest, and "Lord of June" for its abundance during the summer season. It also is the official insect for the state of Washington.
