The insect order Neuroptera, or net-winged insects, includes the lacewings, mantidflies, antlions, and their relatives. The order consists of some 6,000 species . [ 1 ] Neuroptera is grouped together with the Megaloptera ( alderflies , fishflies , and dobsonflies ) and Raphidioptera (snakeflies) in the unranked taxon Neuropterida (once known as ...
Neoptera (Ancient Greek néos ("new") + pterón ("wing")) is a classification group that includes most orders of the winged insects, specifically those that can flex their wings over their abdomens. This is in contrast with the more basal orders of winged insects (the " Palaeoptera " assemblage), which are unable to flex their wings in this way.
They were formerly grouped together with the Palaeoptera and Paraneoptera as the Hemimetabola or Exopterygota on the grounds that they have no pupa, the wings gradually developing externally throughout the nymphal stages. [2] Many members of the group have leathery forewings and hindwings with an enlarged anal field (vannus).
The dustywings, Coniopterygidae, are a family of Pterygota (winged insects) of the net-winged insect order ().About 460 living species are known. [1] These tiny insects can usually be determined to genus with a hand lens according to their wing venation, but to distinguish species, examination of the genitals by microscope is usually necessary.
Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax ), and the two pairs are often referred to as the forewings and hindwings , respectively, though a few insects lack hindwings, even rudiments.
The wings are usually translucent with a slight iridescence; some have green wing veins or a cloudy brownish wing pattern. The vernacular name "stinkflies", used chiefly for Chrysopa species but also for others (e.g. Cunctochrysa) refers to their ability to release a vile smell from paired prothoracic glands when handled.

Others, such as earwigs, provide maternal care, guarding their eggs and young. Insects can communicate with each other in a variety of ways. Male moths can sense the pheromones of female moths over great distances. Other species communicate with sounds: crickets stridulate, or rub their wings together, to attract a mate and repel other males.
'winged') is a subclass of insects that includes all winged insects and groups who lost them secondarily. [3] Pterygota group comprises 99.9% of all insects. [4] The orders not included are the Archaeognatha (jumping bristletails) and the Zygentoma (silverfishes and firebrats), two primitively wingless insect orders. Unlike Archaeognatha and ...
