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.

新翅下纲（学名： Neoptera ），包含昆蟲綱 有翅亞綱下，除古翅下纲 （Palaeoptera）之外的所有物种，此類的昆蟲擁有翅膀，也包含在演化过程中失去了翅膀，没有飞行能力的物種 [2] 。

Neoptera is a major taxonomic group of insects that includes almost all the winged insects and specifically those considered to be related by the ability to fold their wings back over their abdomen. Traditionally, they are one of two major groups within the subclass Pterygota (the winged insects), the other being Paleoptera, which lack the ...

新翅下纲（学名：Neoptera），包含昆虫纲有翅亚纲下，除古翅下纲 （Palaeoptera）之外的所有物种，此类的昆虫拥有翅膀，也包含在演化过程中失去了翅膀，没有飞行能力的物种。

The Neoptera are defined by the ability to swivel and fold the wings back at rest. The functional significance of such a modification is obvious—it allows the insect the opportunity to slip into small places to hide from predators and seek food.

Neoptera is a classification group that has almost all the winged insects, mostly those that can flex their wings over their abdomens. This is in contrast with the more basal orders of winged insects, which are not able to flex their wings in this way.

The neopterous insects include the Hemipteroid Assemblage, Endopterygota, as well as the "lower Neoptera". The "lower Neoptera" include the Plecoptera, Embidiina, Zoraptera, and the "orthopteroid" orders (all the remaining living orders shown in the tree above).

有翅昆虫可以分为古翅下纲（Paleoptera）和新翅下纲（Neoptera）。 二者的翅结构有很大区别，有观点认为古翅类和新翅类的飞行能力是分别独立演化的。 图片来源自[5]。

2008年6月20日 · Neoptera noun - the majority of orders of winged insects--they have a sophisticated mechanism for folding the wing. According to this Tree of Life article there are three prominent evolutionary lines of living winged insects:
