Does the grasshopper or caterpillar undergo incomplete metamorphosis

The phenomenon called incomplete metamorphosis is seen in grasshopper.

The total number of the stages act as major difference between incomplete and complete metamorphosis. The former has 3 stages namely egg, nymph and adult, whereas the latter has 4 stages namely egg, larva, pupa and adult.

The process of incomplete metamorphosis is seen in insects such as grasshopper, termites, true bugs, praying mantis etc. The caterpillar shows complete metamorphosis at the end of which adult butterfly emerges out.  

In incomplete metamorphosis, initially, the insect comes out of egg. Then it grows and becomes nymph which is a smaller version of adult insect, its physical appearance is very vulnerable due to its young age. Then it grows into a adult insects and lives till its end.
