Aeshna
''Aeshna'', or the mosaic darners, is a genus of dragonflies from the family Aeshnidae. Species within this genus are generally known as "hawkers" (Old World) or "darners" (New World). Description These are relatively large dragonflies. Their thoraces and abdomens are brown in color, with blue or yellow stripes or spots on the thorax, and yellow, blue or green spots on the abdomen. Natalia von Ellenrieder's 2003 paper demonstrated that the Holarctic and Neotropical species placed in this genus did not share a common ancestor, and proposed the latter be placed in the genus '' Rhionaeschna''. The name ''Aeshna'' was coined by the Danish entomologist Fabricius in the 18th century. The name may have resulted from a printer's error in spelling the Greek ''Aechma'', "a spear". The spelling ''Aeschna'' has been intermittently used over a period of time, but is now abandoned for the original name ''Aeshna''. However, derived genus names (such as '' Rhionaeschna'') retain the 'sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Southern Hawker
The southern hawker or blue hawker (''Aeshna cyanea'') is a species of hawker dragonfly. Distribution The species is one of the most common and most widespread dragonflies in Europe. The total range is West Palearctic and covers a large part of Europe (to Scotland and southern Scandinavia in the North to Italy (without the Southwest) and the northern Balkans to the South); the Eastern boundary is formed by the Ural and the West by Ireland. It is also found in Northwest Africa (Algeria). In Central Europe the species is very common. Habitat These dragonflies mainly inhabit well-vegetated, small ponds and garden ponds, but they wander widely, and they are often seen in gardens and open woodland. Description ''Aeshna cyanea'' can reach a body length of about , with a wingspan up to .Richard Robinson Askew, The Dragonflies of Europe, Harley Books, 2004, p. 109.

Aeshna Affinis
''Aeshna affinis'', the southern migrant hawker or blue-eyed hawker, is a dragonfly found in southern Europe and Asia. It is in the family Aeshnidae and is very similar in appearance to '' A. mixta''. Identification ''Aeshna affinis'' is a small ''Aeshna'' and very similar to the related '' A. mixta'' with which it is easily confused. As its name suggests the male has blue eyes and also blue marking on the abdomen. ''A. affinis'' lacks the yellow T-shaped mark which is found on the top of the second abdomen segment in ''A. mixta''. The markings on the side of the thorax are also different in ''A. affinis'' and ''A. mixta''. In ''A. affinis'' the sides of the thorax are greeny yellow with fine black lines along the sutures. In ''A. mixta'' the sides of the thorax are similar in colour but the yellow is separated by dark brown areas so it gives the appearance of having two broad yellow stripes Distribution and habitat ''Aeshna affinis'' is found in southern and central Europe an ...

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 ...
