The butterfly's wings are initially soft and shriveled, but they expand and harden within a few hours. What emerges from the chrysalis is a fully formed adult-a butterfly. In reality, though, the larval tissues completely break down and reorganize within the pupal skin. From the outside, it appears as though the pupa, also known as the chrysalis, is resting. The caterpillar then enters the pupal stage, when it neither feeds nor moves. The caterpillar undergoes several molts of its skin until it becomes full grown and has accumulated enough body mass to carry it through the entire life cycle, including the adult phase. After hatching from the egg, the young caterpillar spends most of its time eating leaves and gaining weight. The wormlike butterfly larva, or caterpillar, looks nothing like a winged adult. “Bug Talk” by Will Collier (BMI) / Warner/Chappell Production Music Generous support for The Butterfly Conservatory has been provided by the Eileen P.
