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 .
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 ...
This is a list of species of damselflies and dragonflies recorded in Australia. Common names of species are linked, beside their scientific names. The list is split into two groups: damselflies (suborder Zygoptera) and other dragonflies (infraorder Anisoptera). Those groups are organized in Families and then Genera and Species.
Coenagrionidae is a family of damselflies, also known as pond damselflies, in the order Odonata and the suborder Zygoptera. [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.
