What are the stages of complete metamorphosis?

The stages of complete metamorphosis in insects are indeed classified as egg, larva, pupa, and adult. This process involves a significant transformation that allows the organism to undergo distinct changes in morphology and behavior through its life cycle.

Starting from the egg stage, the insect hatches into a larva, which is primarily focused on feeding and growth. The larval stage can vary significantly in form and behavior depending on the species, but generally, it is a relatively active and voracious stage.

After the larval stage, the next phase is the pupa or chrysalis. This stage is crucial as it is where the insect undergoes a remarkable transformation. Inside the pupal casing, the structure and organization of the larva are radically altered, preparing the organism for its adult form.

Finally, upon completion of the pupal stage, the mature insect emerges as an adult, fully developed and capable of reproduction. This complete metamorphosis allows insects to exploit different ecological niches and can improve their chances of survival and reproductive success across their life cycle.

The distinction in this process is significant because it contrasts with incomplete metamorphosis, which typically involves fewer stages, such as nymphs that resemble smaller adults rather than undergoing a pupal
