Odonata is an order of predatory flying insects that includes the dragonflies and damselflies.The two groups are distinguished with dragonflies (suborder Epiprocta) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and wings folded together along body at rest.
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of dragonflies are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterised by a pair of large ...
Cordulegastridae. The Cordulegastridae are a family of Odonata ( dragonflies) from the suborder Anisoptera. They are commonly known as spiketails. [ 2] Some vernacular names for the species of this family are biddie and flying adder. [ 3] They have large, brown or black bodies with yellow markings, and narrow unpatterned wings.
In most Odonata there is a structure on the leading edge near the tip of the wing called the pterostigma. This is a thickened, hemolymph –filled and often colorful area bounded by veins. The functions of the pterostigma are not fully known, but it most probably has an aerodynamic effect [4] and may also have a visual function.
There are 57 recorded species of Odonata in Britain, made up of 21 damselflies (suborder Zygoptera) and 36 dragonflies (suborder Anisoptera). Of these, 42 species (17 damselflies and 25 dragonflies) are resident breeders, and the remainder are either extinct species, or vagrants - in respect of the latter, this list follows the decisions of the Odonata Records Committee.

[ 2 ] The Zygoptera are the damselflies, which although less known than the dragonflies, are no less common. More than 1,300 species are in this family, making it the largest damselfly family.
