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] |

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 ...
