Common Green Darner

<em>Anax junius</em>, commonly known as the common green darner, is a large dragonfly belonging to the genus Anax within the family Aeshnidae. This species occupies virtually all terrestrial and freshwater habitats, and its range is centered on the United States, where it is one of the most recognizable and widespread dragonfly species. Common green darner is assessed as Least Concern on the IUCN Red List. The species is well known for undertaking long-distance migrations, with populations moving southward in autumn and northward in spring across North America. Adults are typically found near ponds, lakes, and slow-moving streams where females deposit eggs in aquatic vegetation. Biological traits of this species remain poorly documented in the scientific literature.
