Exopterygota

Etymology
From +  +, reflecting the fact that the nymphs (larvae) of winged species bear their wing rudiments externally; compare.

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.
