[why are insects so successful]To mature and integrate into the natural world, insects must go through many important stages in life. It may take several days or even years to complete their morphological transformation.
What is metamorphosis?
Except for some special cases, all insects start their lives in an egg. After leaving the egg, the insect grows and changes its form until it matures. Only adult insects can mate and breed. The transformation of an insect's body from one stage to another in the life cycle is called metamorphosis.
Insects undergo a gradual transformation, which includes subtle or complete transformation. In which each stage of the life cycle in each species may be different.

Little or no metamorphosis
The oldest insects, such as springtails, experience very little or no actual metamorphosis in their lifetime. Entomologists classify these insects as ametabolous, which in Greek means "without metamorphosis".
In non-metamorphic insects, the young are a small version of an adult when it comes out of its shell.
The calves will grow until they reach adulthood. This insect includes the silver bug and the flying tail beetle.

Simple or incomplete metamorphosis
During incomplete metamorphosis, there are three stages that occur in the cycle, including eggs, larvae, and maturation. Metamorphic insects are not completely called hemimetabolous (Hemi means apart). Some entomologists consider this type of metamorphosis to be an incomplete metamorphosis.
The development occurs in the larval stage. Larvae have many similar characteristics of adulthood. Usually, the larvae also live in the same habitat and eat the same food source as adults and have some similar behaviors. For winged insects, the larvae grow wings through skin peeling and the wings are slowly developed. When the functions in the body and wings develop, they are considered mature.
Metamorphosis completely
Most insects undergo a complete transformation with four stages in the life cycle: eggs, larvae, nymphs, and adults - different from the above metamorphosis types. Entomologists call these insects holometabolous (holo means complete).
In this metamorphosis type, the larvae do not have the same characteristics as adults. They molt and develop often several times before evolving the pupae.
In some insect families, there are many different names for their larvae. For example, the larvae of butterflies and moths are called caterpillars, the larvae of flies are maggots, and larvae of beetles are called grubs.
When the larva molt for the last time, it perverts into a pupa. This period is often referred to as the rest period, although many activities occur inside that we cannot see. The larvae and organs decompose completely, then reorganize into an adult form. After the stages of transformation inside the pupa are completed, the pupil finally molts and exposes its adult form with wings and full function.
