Detailed explanation-1: -In holometabolous insects, immature stages are called larvae and differ markedly from adults. Insects which undergo holometabolism pass through a larval stage, then enter an inactive state called pupa (called a “chrysalis” in butterfly species), and finally emerge as adults.

Detailed explanation-2: -Insects with complete metamorphosis have four (4) life stages: egg, larva, pupa and adult. Larvae are very different in form from the adult. The active immature stages are known generally as larvae. These insects also have a resting stage known as a pupa.

Detailed explanation-3: -pupa, plural pupae or pupas, life stage in the development of insects exhibiting complete metamorphosis that occurs between the larval and adult stages (imago). During pupation, larval structures break down, and adult structures such as wings appear for the first time.

Detailed explanation-4: -The life cycle of holometabolous insects (those which undergo complete metamorphosis) includes four distinct stages: egg, larva (caterpillar), pupa (chrysalis) and adult.

Detailed explanation-5: -Complete Metamorphosis: Complete metamorphosis consists of four stages: egg, larva, pupa, and adult. Incomplete Metamorphosis: Incomplete metamorphosis consists of three stages: egg, nymph, and adult.
