Gradual metamorphosis is typical of true bugs and grasshoppers; complete metamorphosis is typical of butterflies, beetles, flies, moths, and wasps. The immature of the butterflies, beetles flies moths and wasps do not resemble the adults, may occupy different habitats, and feed on different hosts.
Others again consider that the whole cycle is a metamorphosis which, beginning in the Heterocotylea as a direct development, has become complicated in the Holostomidae by a larval history, and finally in the Malacocotylea has acquired additional complexity by the intercalation of two larval forms, and is thus spread over several generations.
