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 ...
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 ...
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.
Articles relating to the Odonata, an order of flying insects that includes the dragonflies and damselflies. Members of the group first appeared during the Triassic , though members of their total group , Odonatoptera , first appeared in Late Carboniferous .
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies (which constitute the other odonatan suborder, Epiprocta) but are usually smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body.
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 Gomphidae are a family of dragonflies commonly referred to as clubtails or club-tailed dragonflies.The family contains about 90 genera and 900 species found across North and South America, Europe, Asia, Australia, and Africa. [2]
