The process when a caterpillar transforms into a butterfly is called metamorphosis. This fascinating process involves several stages: egg, larva (caterpillar), pupa (chrysalis), and adult (butterfly). After hatching, the caterpillar feeds voraciously to grow, then forms a pupa, during which it undergoes significant transformation. Inside the chrysalis, the caterpillar's body is restructured to develop into a butterfly. This transformation can take several weeks, depending on the species and environmental conditions. Once mature, the butterfly emerges from the chrysalis, ready to fly and complete its life cycle, often emphasizing the beauty and complexity of nature.
