The larva and the pupa represent two stages of an insect's life. After an egg hatches, an insect enters the first active phase of life and becomes a larva. The larva's main job is to feed and store energy. The pupa is the next stage of an insect's life. Although the larva feeds constantly, the pupa usually does not feed and appears motionless. Unless it lives inside a stem or a leaf, the pupa builds a protective outer shell called a cocoon. Inside the cocoon, the pupa transforms from a soft, worm-like creature into a new physical form, such as a butterfly or a moth. Unlike the pupa, a larva doesn't build a cocoon and remain inside. Instead, the larva is busy eating—and often destroying—agricultural crops.
