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.
- A taxonomic superorder within the infraclass Neoptera—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.
