The Exopterygota are a superorder of insects. They are in the subclass Pterygota in the infraclass Neoptera.
In Exopterygotes the young resemble adults but have externally-developing wings. They undergo a modest change between immature and adult, without going through a pupal stage. The nymphs develop gradually into adults through a process of moulting.
The Exopterygota are a diverse insect superorder, divided into eight orders. They include locusts, thrips, and lice among other types of insects.
