description Racket-tailed Emerald Overview
The Racket-tailed Emerald (Dorocordulia libera) is a species of dragonfly in the Corduliidae family, native to the northeastern regions of North America. Formally described in 1871, the insect takes its common name from the male's distinctly clubbed abdomen, which features an expanded, paddle-like tip. Both sexes exhibit the metallic green coloration typical of emerald dragonflies, though their eyes develop a bright green hue in mature adults. They are typically found inhabiting boggy meadows, marshes, and the vegetated margins of woodland ponds.
