Pinheyschna Subpupillata
''Pinheyschna subpupillata'', the stream hawker, is a species of dragonfly in the family Aeshnidae. Distribution This hawker is endemic to southern Africa; it is common in much of southern and eastern South Africa, and is also found in parts of Mozambique and Zimbabwe. Habitat Its natural habitats include fast-flowing streams and rivers in montane and upland settings. Rivers and streams with densely vegetated banks (both grassy and bushy) are preferred. Description A large dragonfly (length 61–64 mm; wingspan 87–91 mm). The eyes are green and the face deep yellow to greenish yellow; the upper frons has a central black spot within a yellow ring. The thorax is brown with green stripes, and the abdomen green with brown markings. The wings are slightly smoky with brown and yellow veins and reddish-brown to yellow-brown pterostigmata. Similar species ''Pinheyschna subpupillata'' is similar to ''Zosteraeschna minuscula'' and ''Zosteraeschna usambarica'', but the la ...

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 and among the largest dragonflies on the planet. Description Common worldwide or nearly worldwide genera are '' Aeshna'' and '' 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 flight. The eggs are deposited in water or close by. The larvae (nymphs or naiads) are generally slender compared to those of other families, with a long and flat extensible lower lip (labium). The larvae are aquatic predators, feeding on other insects and even small fish. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 demo ...

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 ...

Philip Powell Calvert
Philip Powell Calvert (January 29, 1871 – August 23, 1961) was an American entomologist, recognised as a leading authority on the Odonata (dragonfly order). A long term teacher and professor at the University of Pennsylvania, he was President of the American Entomological Society 1900-15. His 1893 publication ''Catalogue of the Odonata (dragonflies) of the Vicinity of Philadelphia, with an Introduction to the Study of this Group'' served as a model for regional insect study and was the first major attempt at a guide to the order. Calvert went on to publish over 300 notes and articles on the Odonata. He was married to botanist Amelia Smith Calvert.
