The correct sequence in the life cycle of a moth is egg, larva, pupa, adult. This sequence reflects the complete metamorphosis that moths undergo, which consists of four distinct stages.

Starting from the egg, the life cycle begins when a female moth lays eggs. These eggs hatch into larvae, commonly known as caterpillars, which are the feeding and growth phase of the moth. During this stage, the larvae consume food voraciously to grow in size. After sufficient growth, the larvae enter the pupa stage, where they undergo a transformation. Inside the pupa, they develop into their adult form through a process called metamorphosis. Finally, the adult moth emerges from the pupa and can then reproduce, completing the cycle by laying eggs once more.

This understanding of the life cycle is fundamental in studying entomology and biology, as it illustrates the various developmental stages that many insects, including moths, experience.
