Metamorphosis: Kinds, Events and Role of HormonesIn this article we will discuss about Metamorphosis in Insects:- 1. Meaning of Metamorphosis 2. Types of Metamorphosis 3. Events 4. Role of Hormones.Meaning of Metamorphosis:Metamorphosis can be defined as “a rapid and complete transfor­mation from an immature larval life to a sexually adult form involving morphology, function and habitat changes”.Ecdysis or moulting is the periodic shed- ding off the old exoskeleton. The duration of the period between two successive moults of a developing insect is called stadium. The form of the developing insect between two moults is called instar.A larva is a motile, immature feeding stage in arthropods which is morphologi­cally different from the adult stage. The larvae of hemimetabolous insects are called nymphs. The adult stage of holometabolous insects is called imago.Types of Metamorphosis:On the basis of degree of changes there are 5 basic types of metamorphosis seen in insects.They are:(1) Ametabolous deve­lopment or Ametamorphic2) Gradual meta­morphosis or Paurometabolous develop­ment(3) Incomplete metamorphosis or Hemimetabolous development(4) Complete metamorphosis or Holometabolous devel­opment and(5) Hypermetamorphosis or Hypermetabolous development.
