Exopterygota

From exo- (“outside”) +‎ pterygo- (“wing”) +‎ -ota (“having”), reflecting the fact that the nymphs (larvae) of winged species bear their wing rudiments externally; compare Endopterygota.

Exopterygota

1. A taxonomic superorder within the class Insecta – various winged insects that undergo incomplete metamorphosis.

Not commonly used.

The Exopterygota differ from the Endopterygota in that they generally undergo an "incomplete" metamorphosis. Their life cycle typically lacks a clearly defined pupal phase. In winged species the nymphs (larvae) generally bear external wing rudiments, which immature members of the Endopterygota do not.

The Exopterygota life cycle is: egg → larva or nymph → adult or imago. The transformation from larva to adult is gradual and proceeds by moulting.

For comparison, the complete metamorphosic life cycle is: egg → larva → pupa → adult or imago.
