Exopterygota

Translingual

Etymology

From Ancient Greek ἔξω (éxō, “outside”) + πτερόν (pterón, “wing”) + New Latin -ota (“having”), reflecting the fact that the nymphs (larvae) of winged species bear their wing rudiments externally; compare Endopterygota.

Proper noun

Exopterygota

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

Usage notes

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.
