Cordulia is a genus of dragonfly in the family Corduliidae. [1] [2] [3]
The genus includes three species: [4]
The Corduliidae, also knowns as the emeralds, emerald dragonflies or green-eyed skimmers, is a family of dragonflies. These dragonflies are usually black or dark brown with areas of metallic green or yellow, and most of them have large, emerald-green eyes. The larvae are black, hairy-looking, and usually semiaquatic. This family include species called "baskettails", "emeralds", "sundragons", "shadowdragons", and "boghaunters". They are not uncommon and are found nearly worldwide, but some individual species are quite rare. Hine's emerald dragonfly, for example, is an endangered species in the United States.
The orange-spotted emerald is a dragonfly in the family Corduliidae. It is the only species in its genus.
Celithemis is a genus of dragonflies in the family Libellulidae. They are known commonly as pennants. There are eight species in this monophyletic genus. They are mainly distributed in eastern North America.
