  Odonata - Wikipedia, the free encyclopedia
Odonata is an order in the class Insecta, encompassing those insects commonly known as dragonflies (either when referring to the group as a whole, or for the species in the suborder Epiprocta in a general or the infraorder Anisoptera in a strict sense) and damselflies (for the species in the suborder Zygoptera).
It was long believed that the Anisoptera were a suborder and that there existed a third one, the Anisozygoptera (ancient dragonflies).
However, they were combined in the suborder Epiprocta (in which Anisoptera is an infraorder) after it was revealed that the Anisozygoptera are a paraphyletic group composed of mostly extinct offshoots of dragonfly evolution.

 Dragonfly - Wikipedia, the free encyclopedia
It is characterized by large multifaceted eyes, two pairs of strong transparent wings, and an elongated body.
Conventionally, the Anisoptera were given suborder rank besides the "ancient dragonflies" (Anisozygoptera, 2 living species and numerous fossil ones), but it has been determined recently that the Anisozygoptera form a paraphyletic assemblage of primitive relatives of the Anisoptera.
Thus, the Anisoptera are reduced to an infraorder, forming the new suborder Epiprocta (dragonflies in a general sense).

In Zygoptera is het abdomen slank en cilindrisch, in Anisoptera meestal breed en afgeplat.
De meeste Anisoptera leggen hun eieren direct in het water door onderdompeling van het achterlijf of de eieren worden los over het water uitgestrooid; indien voorzien van een legapparaat, zoals de Zygoptera, worden de eieren in ondergedompelde plantendelen of modder gestoken.
Anisoptera kunnen voorwaarts schieten door wateruitstoot uit hun anale kieuwsysteem.

 Odonate Wing Venation   (Site not responding. Last check: 2007-10-09)
The Comstock and Needham (1898) wing vein naming system, still widely used by dragonfly workers in the United States, implies that the common ancestor of modern Odonata was anisopteran and that the zygopteran venation is arrived at by reduction.
The Tillyard (1917) version of this system implied Zygoptera is sister to Anisoptera but reconciled wing vein patterns across the suborders by giving different names to veins in the same position on the wing.
If this is correct (and it has yet to be tested) one implication for the history of wing venation would be that the expanded hind field of Anisoptera is secondarily derived and veins in that region of the wing are not homologous with the veins found in other insects.

They are more common in warmer parts of the world than in temperate areas like the UK and of the 5 300 named species world-wide, only 38 live and breed in Britain.
They are conveniently divided up into two groups Anisoptera the true Dragonflies which rest with their wings out from their body in a cross shape and Zygopteran or Damselflies who hold their wings above their body.
Anisoptera means 'unequal wings' and generally speaking the members of this suborder have their hindwings broader than their forewings.
