Orthetrum
''Orthetrum'' is a large genus of dragonfly, dragonflies in the Libellulidae family. They are commonly referred to as skimmers. The size of adults within the genus ranges from small to large; in Africa, the hindwing ranges in length from 22 to 50 mm. The bodies of adult females and recently emerged males are yellow to brown with black markings; these may facilitate identification of individuals to species level. Mature males, however, develop blue-grey pruinosity over most of their bodies - this makes species identification difficult without the capture of a specimen and inspection of the shape of the hamule.

Orthetrum Albistylum (young Female) (1)
''Orthetrum albistylum'' is a dragonfly species, which occurs from central and south Europe to China and Japan. Its distribution is often patchy but in many areas it is common. The species has recently spread its range northwards to the Baltic Sea coast in Poland. The common name for this species is white-tailed skimmer. One of the ongoing threats affecting the habitat of Orthetrum albistylum is the production of crops. The water pollution associated with crop production is also having a direct effect on the quality of the habitat of this species.

Libellulidae
The skimmers or perchers and their relatives form the Libellulidae, the largest dragonfly family in the world. It is sometimes considered to contain the Corduliidae as the subfamily Corduliinae and the Macromiidae as the subfamily Macromiinae. Even if these are excluded (as Silsby does), there remains a family of over 1000 species. With nearly worldwide distribution, these are almost certainly the most often seen of all dragonflies. The genus ''Libellula'' is mostly New World, but also has one of the few endangered odonates from Japan: ''Libellula angelina''. Many of the members of this genus are brightly colored or have banded wings. The related genus ''Plathemis'' includes the whitetails. The genus ''Celithemis'' contains several brightly marked species in the southern United States. Members of the genus ''Sympetrum'' are called darters (or meadowhawks in North America) and are found throughout most of the world, except Australia.

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 ...
