Metamorphosis Insects Incomplete metamorphosis or 'hemimetabolism'
Insects with incomplete metamorphosis have three life stages. These insects start as eggs, which are usually very small. When the egg hatches, a larva or nymph comes out. Nymphs are just baby insects. Most of the time, the nymph looks similar to the adult, but it is smaller, may have different colouration, and does not have wings. Finally, it changes into a mature adult with wings.
