Polyneoptera

The cohort Polyneoptera is one of the major groups of winged insects, comprising the Orthoptera (grasshoppers, crickets, etc.) and all other neopteran insects believed to be more closely related to Orthoptera than to any other insect orders. 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 (tegmina) and hindwings with an enlarged anal field (vannus).
