Gomphurus Modestus
''Gomphurus modestus'', the Gulf Coast clubtail, is a species of dragonfly in the family Gomphidae. It is endemic to the southeastern United States, and is found in medium to large, slow-flowing rivers over rock, mud and sand substrates. This species was formerly a member of the genus '' Gomphus''. It is now considered to be a member of the genus ''Gomphurus ''Gomphurus'' is a genus of clubtails in the family of dragonflies known as Gomphidae. There are about 13 described species in ''Gomphurus''. ''Gomphurus'' was formerly considered a subgenus of ''Gomphus (dragonfly), Gomphus'', but has recently ...'', after that name was elevated in rank from subgenus in 2017. The IUCN conservation status of ''Gomphurus modestus'' is "LC", least concern, with no immediate threat to the species' survival. The population is stable. The IUCN status was reviewed on 5 May 2016.

Dragonfly
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 or ...

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] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gomphus (dragonfly)
''Gomphus'' is a genus of clubtail dragonflies in the family Gomphidae. As a result of phylogenetic studies, ''Gomphus'' subgenera ''Gomphurus'', ''Hylogomphus'', ''Phanogomphus'', and ''Stenogomphurus'' were elevated in rank to genus in 2017. With the removal of their member species, ''Gomphus'' ended up with 11 of its previous 54 species, none of which are found in the Western Hemisphere. Species These 11 species belong to the genus ''Gomphus'': These species formerly belonged to the genus ''Gomphus'': * ''Gomphurus crassus'' (Hagen in Selys, 1878) (handsome clubtail) * ''Gomphurus dilatatus'' (Rambur, 1842) (blackwater clubtail) * ''Gomphurus externus'' (Hagen in Selys, 1858) (plains clubtail) * ''Gomphurus fraternus'' (Say, 1840) (midland clubtail) * ''Gomphurus gonzalezi'' (Dunkle, 1992) (tamaulipan clubtail) * ''Gomphurus hybridus'' (Williamson, 1902) (cocoa clubtail) * ''Gomphurus lineatifrons'' (Calvert, 1921) (splendid clubtail) * ''Gomphurus lynnae'' (Paulson, ...

Insects Of The United States
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...
