The Aeshnidae, also called aeshnids, hawkers, or darners, is a family of dragonflies. The family includes the largest dragonflies found in North America and Europe and among the largest dragonflies on the planet.
The skimmers or perchers and their relatives form the Libellulidae, the largest dragonfly family in the world. It is sometimes considered to contain the Corduliidae as the subfamily Corduliinae and the Macromiidae as the subfamily Macromiinae. Even if these are excluded, there remains a family of over 1000 species. With nearly worldwide distribution, these are almost certainly the most often seen of all dragonflies.
The insect family Coenagrionidae is placed in the order Odonata and the suborder Zygoptera. The Zygoptera are the damselflies, which although less known than the dragonflies, are no less common. More than 1,300 species are in this family, making it the largest damselfly family. The family Coenagrionidae has six subfamilies: Agriocnemidinae, Argiinae, Coenagrioninae, Ischnurinae, Leptobasinae, and Pseudagrioninae.
The Gomphidae are a family of dragonflies commonly referred to as clubtails or club-tailed dragonflies. The family contains about 90 genera and 900 species found across North and South America, Europe, Asia, and Australia. The name refers to the club-like widening of the end of the abdomen. However, this club is usually less pronounced in females and is entirely absent in some species.
Sympetrum is a genus of small to medium-sized skimmer dragonflies, known as darters in the UK and as meadowhawks in North America. The more than 50 species predominantly live in the temperate zone of the Northern Hemisphere; no Sympetrum species is native to Australia.
Ceriagrion is a genus of damselfly in the family Coenagrionidae. Species of Ceriagrion are small to medium size, generally brightly coloured damselflies. They are found across the Old World, Africa, Asia and Australia.
Chlorogomphus is a genus of dragonfly in the family Chlorogomphidae.
Gynacantha is a genus of dragonflies in the family Aeshnidae. The females have two prominent spines under the last abdominal segment. This gives the genus name and the common name two-spined darners; they are also known as duskhawkers.
Hemicordulia is a genus of dragonfly in family Corduliidae. It occurs in Africa, southern Asia, Australasia and Pacific Islands such as the Bonin Islands, Fiji and French Polynesia. Species of Hemicordulia are small to medium-sized dragonflies, coloured black or metallic, with yellow.
Ischnura is a genus of damselflies known as forktails in the family Coenagrionidae. Forktails are distributed worldwide, including various oceanic islands. The males have a forked projection at the tip of the abdomen which gives the group their common name.
Leptogomphus is a genus of dragonfly in the family Gomphidae. It contains the following species:
Pseudagrion is the largest genus of damselfly in the family Coenagrionidae, with over 140 species. Its range includes most of Africa, much of Asia, and Australia. Africa holds most of the diversity with almost 100 species. It has occupied most of the freshwater habitats in its range, and dominates damselfly communities in habitats as different as desert pools, equatorial rainforests and montane streams.
Rhinocypha is a genus of damselflies in the family Chlorocyphidae.
Anax is a genus of dragonflies in the family Aeshnidae. It includes species such as the emperor dragonfly, Anax imperator.
Vestalis is a genus of damselflies belonging to the family Calopterygidae.
