Dragonflies
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonfly are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterized by a pair of large, multifaceted compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural colouration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along ...

Petaluridae
The petaltails of the family Petaluridae are apparently the most ancient of the extant true dragonflies (infraorder Anisoptera), having fossil members from as early as the Jurassic (over 150 million years ago). Modern petalurids include only 11 species, one of which, the Australian ''Petalura ingentissima'', is the largest of living dragonflies, having a wingspan of up to 160 mm and a body length of over 100 mm. Other Australian species include ''Petalura gigantea'' (commonly known as the giant dragonfly). In the United States, two species are found, one on either coast. The larvae live primarily in stream banks, mostly in burrows, but the larvae of the eastern US species, ''Tachopteryx thoreyi ''Tachopteryx thoreyi'', commonly known as the gray petaltail and Thorey's grayback, is a species of dragonfly. It is native to the East Coast of the United States as far north as New York, as far south as Florida, and as far west as Texas. This ...'', the gray petaltail, liv ...

Austropetaliidae
Austropetaliidae is a small family of dragonflies occurring in Chile, Argentina and Australia. Members of Austropetaliidae can be medium-sized to large dragonflies. This group was initially created for some archaic members of the family Neopetaliidae and was promoted to family rank in 1994. Genera The family includes the following genera: * ''Austropetalia'' * ''Archipetalia'' * '' Hypopetalia'' * ''Phyllopetalia ''Phyllopetalia'' is a genus of dragonflies in the family Austropetaliidae. They are commonly known as Redspots. All the species are endemic to Chile except for ''P. pudu'' which also occurs in Argentina Argentina (), officially the A ...''

Aeshnidae
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 Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia ... and among the largest dragonflies on the planet. Description Common worldwide or nearly worldwide genera are ''Aeshna'' and ''Anax (dragonfly), Anax''. The African ''Anax tristis'' has a wingspan over 125 mm, making it one of the world's largest known dragonflies. There are 41 North American species in 11 genera in this family. Most European species belong to ''Aeshna''. Their American name "darner" stems from the female abdomens looking like a sewing needle, as they cut into plant stem when they lay their eggs through the ovipositor. The dragonflies mate in fligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gomphidae
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 (abdominal segments 7 through 9). However, this club is usually less pronounced in females and is entirely absent in some species. Etymology The name may be derived from Latin ''gomphus'' or ''gond'' meaning "hinge". Characteristics Clubtails have small, widely separated compound eyes, a trait they share with the Petaluridae and with damselflies. The eyes are blue, turquoise, or green. The thorax in most species is pale with dark stripes, and the pattern of the stripes is often diagnostic. They lack the bright metallic colors of many dragonfly groups and are mostly cryptically colored to avoid detection and little difference between the sexes is seen. Adults are usually from in length; there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ictinogomphus Rapax
''Ictinogomphus rapax'', the common clubtail, is a species of dragonfly in the family Gomphidae. It is found throughout the Indomalayan realm, Indomalayan region. Description and habitat It is a large yellow and black colored dragonfly with bluish-grey eyes. The thorax is black, marked with yellow or greenish-yellow stripes.

Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family (biology), family, order (biology), order, class (biology), class, phylum (biology), phylum, kingdom (biology), kingdom, domain (biology), domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of phenotypic trait, traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
