How do insects such as butterflies grow and change?

Insects like butterflies undergo a process called metamorphosis, which involves four distinct stages: egg, larva (caterpillar), pupa (chrysalis), and adult. After hatching from eggs, caterpillars feed and grow, shedding their skin multiple times. Eventually, they enter the pupal stage, where they undergo significant transformation inside the chrysalis. Finally, they emerge as adult butterflies, ready to reproduce and continue the cycle.
