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.
Gradualism is selection and variation that happens more gradually. Over a short period of time it is hard to notice.Small variations that fit an organism slightly better to its environment are selected for: a few more individuals with more of the helpful trait survive, and a few more with less of the helpful trait die.hange is slow, constant, and consistent. This definition of gradualism is the result of an earlier definition: gradualism is the principle proposed by Scottish geologist James Hutton in the late 1700s that landforms resulted from slow changes over long periods of time.
