Insects with Complete Metamorphosis

Insects that undergo complete metamorphosis typically appear quite different from the immature to adult stages.  This life history typically has an egg, several larval instars, a pupa, and a final winged adult that is sexually mature.  Unlike insects with incomplete or gradual metamorphosis, the wings of holometabolous insects develop internally.  Some of the most common and recognizable insects have complete metamorphosis, such as butterflies and flies.  Some other insects with complete metamorphosis include the beetles, bees, wasps, ants, and fleas.
