The Exopterygota, also known as Hemipterodea, are a superorder of insects of the subclass Pterygota in the infraclass Neoptera, in which 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 highly diverse insect superorder, with at least 130,000 living species divided between 15 orders. They include termites, locusts, thrips, lice and stick insects, among many other types of insects.
