Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the Epiophlebia damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) 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 ...
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. More mass at the ...
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.
The Odonatoptera are a superorder (sometimes treated as an order) of ancient winged insects, placed in the probably paraphyletic group Palaeoptera.The dragonflies and damselflies (which are placed in the subgroup Odonata) are the only living members of this group, which was far more diverse in the late Paleozoic and contained gigantic species, including the griffinflies (colloquially called ...

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.
The dragonflies Odonata were the dominant aerial predator and probably dominated terrestrial insect predation as well. True Odonata appeared in the Permian [36] [37] and all are amphibian. Their prototypes are the oldest winged fossils, [38] go back to the Devonian, and are different from other wings in every way. [39]
