Zosteraeschna Minuscula
''Zosteraeschna minuscula'', the friendly hawker is a species of dragonfly in family Aeshnidae. It is found in South Africa and Namibia. Its natural habitats include ponds and still pools in montane streams. This is a fairly large species; 59–62 mm long with a wingspan of 76–83 mm. The thorax is brown with green stripes, and the abdomen is brown and blue. The eyes are green. It is similar to '' Pinheyschna subpupillata'' and ''Zosteraeschna usambarica'', but has an anchor- or T-shaped mark on the frons. Males have a blue saddle on the abdomen near the thorax, and females and teneral Ecdysis is the moulting of the cuticle in many invertebrates of the clade Ecdysozoa.

Zosteraeschna Ellioti
''Zosteraeschna ellioti'', the highland hawker or Elliot's hawker, is a species of dragonfly in the family Aeshnidae. It is found in Ethiopia, Kenya, Malawi, Mozambique, South Africa, Tanzania, Uganda, Zimbabwe, and possibly Burundi. Its natural habitats are subtropical or tropical moist montane forests, subtropical or tropical high-altitude shrubland, rivers, freshwater marshes, freshwater springs, and alpine wetland A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months).

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.

Name Of A Biological Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstr ...

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 ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
