HORTICULTURE

Detailed explanation-1: -The house fly has a complete metamorphosis with distinct egg, larval or maggot, pupal and adult stages.

Detailed explanation-2: -Complete metamorphosis has four distinct stages: egg, larva, pupa, and adult.

Detailed explanation-3: -Fruit fly larvae undergo molting stages known as instars, during which the head, mouth, cuticle, spiracles and hooks are shed. During the larva’s third instar, it crawls to a drier area to pupate. The pupa case is formed from the larval skin as it darkens and develops a hard surface.

Detailed explanation-4: -Instar is the name given to the developmental stage of an arthropod between moults. For example, after hatching from the egg and insect is said to be in its first instar. When the insect moults it is then a second instar and so on. Instar can be used for insects undergoing complete and incomplete metamorphosis.
