Detailed explanation-1: -Holometabolism, also called complete metamorphosis, is a form of insect development which includes four life stages: egg, larva, pupa, and imago (or adult).

Detailed explanation-2: -Complete metamorphosis: The immature insects and the adults have different forms, often live in different habitats, and may have very different behavior.

Detailed explanation-3: -Insects fall into one of two categories depending upon their life styles: 4 stage life cycle (complete metamorphosis). The four stages are egg, larva, pupa and adult.

Detailed explanation-4: -Complete, or holometabolous, metamorphosis is characteristic of beetles, butterflies and moths, flies, and wasps. Their life cycle includes four stages: egg, larva (q.v.), pupa (q.v.), and adult. The larva differs greatly from the adult.

Detailed explanation-5: -These insects are often called ‘holometabolous’, meaning they undergo a complete (holo = total) change (metabolous = metamorphosis or change). Those which have immature stages similar in shape to the adult minus the wings are called ‘hemimetabolous’, meaning they undergo partial or incomplete (hemi = part) change.
