B. Larval Stage (Caterpillar)

Once hatched, the egg transforms into a caterpillar, the larval stage. Caterpillars possess distinct characteristics such as segmented bodies, numerous prolegs, and specialized mouthparts for consuming leaves. They feed voraciously, storing energy for the next phase of their life cycle while undergoing multiple molting stages to accommodate their growing bodies.

C. Pupal Stage (Chrysalis)

Following the larval stage, the caterpillar enters the pupal stage within a protective structure called a chrysalis or cocoon. Inside this casing, a remarkable transformation occurs known as metamorphosis. During this phase, the caterpillar undergoes a complete structural rearrangement, forming the wings, legs, and other adult features. The pupal stage concludes with the emergence of the adult butterfly.
