Argia is a genus of damselflies of the family Coenagrionidae and of the subfamily Argiinae. It is a diverse genus which contains about 114 species and many more to be described. It is also the largest genus in Argiinae. They are found in the Western Hemisphere. They are commonly known as dancers. Although the genus name comes from Ancient Greek : ἀργία, romanized: argia, lit. 'laziness', [1] dancers are quite active and alert damselflies. The bluer Argia species may be confused with Enallagma species.
This genus of damselflies are known as dancers because of the distinctive jerky form of flight they use which contrasts with the straightforward direct flight of bluets, forktails and other pond damselflies. They are usually to be seen in the open where they catch flying insects on the wing rather than flying about among vegetation picking off sedentary prey items. They tend to land and perch flat on the ground, logs and rocks. [2] When perched, they usually hold their wing slightly raised above the abdomen. [3]
The males of most species are some combination of black and blue but they can easily be told from similarly coloured bluets by their mode of flight. Some species have red eyes and others a copper-coloured thorax. Many species have humeral stripes, either notched or forked at the end or narrowed in the centre. The wings have short petioles and are relatively broad close to the base. [2] Unlike most of the Coenagrionidae, dancers are often associated with flowing water. [3]
The genus includes the following species:
Additionally a fossil member of this genus is known from the Miocene Mexican amber [7]
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.
Aeshna, or the mosaic darners, is a genus of dragonflies from the family Aeshnidae. Species within this genus are generally known as "hawkers" or "darners".
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.
Rhionaeschna is the scientific name of a genus of dragonflies from the family Aeshnidae. They are also known as blue-eyed darners.
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.
Enallagma is a genus of damselflies in the family Coenagrionidae commonly known as bluets. Adults range in length from 28 mm to 40 mm. Males are usually bright blue and black while the coloration of females varies by species. Bluets can be distinguished from the similar vivid dancer by wing position; at rest, bluets' wings hang down on either side of their body, while vivid dancers hold their wings above their body. Bluets also have shorter leg spines.
Epigomphus is a genus of dragonflies in the family Gomphidae. They are commonly known as Knobtails.
Erythrodiplax is a large Neotropical genus of dragonflies in the family Libellulidae. These small to medium-sized skimmers are commonly known as dragonlets.
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.
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.
Neoneura is a genus of damselfly in the threadtail family Protoneuridae. They are found in the Neotropics, from Cuba and Texas to Argentina.
Palaemnema is a genus of dragonflies in the family Platystictidae. They are commonly known as shadowdamsels and are found in the New World, from Arizona to Peru and French Guiana.
Paraphlebia is a genus of flatwings in the damselfly family Thaumatoneuridae. It was formerly in the subfamily Argiolestinae of the family Megapodagrionidae, but was moved to the family Thaumatoneuridae as a result of molecular phylogenetic studies by Dijkstra et al. in 2013.
Progomphus is a genus of medium-sized dragonflies in the family Gomphidae. They are found in the Americas and are largely tropical. They are one of the few Gomphids with coloured wings.
Protoneura is a genus of damselfly in the family Protoneuridae. It contains the following species:
Aphylla is a widespread Neotropical genus of dragonflies of the Gomphidae family. They are commonly known as the greater forceptails because of their forceps-like cerci.
Anax is a genus of dragonflies in the family Aeshnidae. It includes species such as the emperor dragonfly, Anax imperator.
Telebasis is a genus of damselflies in the family Coenagrionidae. The genus occurs in the Neotropics. Most of the species are red with a few blue species in South America.
Micrathyria is a Neotropical genus of dragonflies. They have bright green eyes and white faces. Most species have a markedly striped thorax. They are commonly known as Tropical Dashers.
Triacanthagyna is a genus of dragonflies in the family Aeshnidae. The species have large eyes and broad wings. The females have three prominent spines under the last abdominal segment which gives the genus its name. They are commonly known as three-spined darners.
