Incomplete metamorphosis has three stages, and complete metamorphosis has four or more stages.
Metamorphosis is basically the cycle through which an insect matures. Complete metamorphosis consist of four stages : egg, larva, pupa and adult. While incomplete metamorphosis has three stages: egg, nymph and adult.
Complete metamorphosis is a 4 stage process from egg, larva, pupa and adult. The young or larva rarely resemble the adult and times for completion can range widely. Butterflies, beetles, fleas all have complete metamorphosis as example.Incomplete is 3 stages from egg, nymph and adult. The young nymphs do look like the adult and simply molt as the grow until full size. Silverfish, firebrats, grasshoppers are examples of incomplete metamorphosis.
A young frog is a tadpole and has a tale and no legs while the adult frog has legs, but no tail.
One advantage to complete metamorphosis is the ability to have a better chance at life. Caterpillars have a better chance of survival when they are butterflies. A disadvantage is the fact that they are vulnerable during the process.
Sorry to jump straight onto this as a newbie, but it got me thinking... The problem with metamorphosis seems to come from the assumption that the process evolved in the same order that it occurs. for example, just because the creature becomes a chrysalis then a butterfly, doesn't mean that the chrysalis evolved before the butterfly. to propose a hypothetical example... A tadpole becomes a frog without the need for a chrysalis. The frog continues to evolve, so that the difference between frog and tadpole increases, and the metamorphosis becomes more complicated. As metamorphosis becomes more complicated, the vulnerability of the organism during the process makes it advantageous for it to be better protected. The individuals with, for example, tougher skin, (at least during the process)are more likely to survive. The tougher skin becomes exagerated until it is distinguishable from the rest of the organism. once the chrysalis has evolved, the extent of the metamorphosis can evolve until it entails a complete decomposition. Any holes in there?
Incomplete metamorphosis have three stages in the life cycle. Complete metamorphosis have four stages in the life cycle.

There are several differences between the two, but the primary is that gradual metamorphosis is a slow, elaborate process. Incomplete metamorphosis has been interrupted and stalled at some point.
Simple metamorphosis involves three stages (egg, nymph, adult) and the nymph gradually resembles the adult with each molt. In complete metamorphosis, there are four stages (egg, larva, pupa, adult) and the larvae and adults have distinctly different body forms and lifestyles.
difference between metamorphosis and moulting
Incomplete metamorphosis involves the animal slowly growing larger through successive moults. The young are called nymphs, and their wings grow externally (like buds) in the early instars. (Eg. grasshoppers, cicadas,etc.) Complete metamorphosis involves separate stages of development; larvae, pupa and adult. (About 90% of insects, including butterflies)
These insects either have hemimetabolous development, and undergo an incomplete or partial metamorphosis, or holometabolous development, which undergo a complete metamorphosis, including a pupal or resting stage between the larval and adult forms. In hemimetabolous insects, immature stages are called nymphs.

Complete metamorphosis is a type of metamorphosis characterized by four frantically different stages: egg, larva, pupa and adult. Gradual metamorphosis is a type of metamorphosis in which an egg hatches into a nymph that resembles an adult, and which has no distinctly different larval stage. They are alike because they both turn into the same thing at the end, an adult. Even though gradual metamorphosis has no larval stage, or it is different, they both turn into an adult.
