The eggs hatch to reveal the larva. Larvae are fairly formless no matter the species.
In the case of butterflies they are called caterpillars - wormlike creatures that do nothing but eat. Flies' larvae are also shaped similarly, but are small, white and have no identifying marks. The larvae do not eat the same food as the adult. In fact, some insects stop eating once they have passed the larva stage. As the larvae grow, they shed their outer exoskeleton several times.
At some point the larva knows to begin a process of becoming a pupa. In this stage, a caterpillar will suspend itself from a branch or other sturdy support and begin to cover itself in a protective covering. Some insects, like bees, have a special place provided for them by the colony to cover themselves up.
This is known as a chrysalis or a cocoon. From the outside it looks as if nothing is happening. But, inside the cocoon, a complete change is happening. The parts of the larva are rearranging — the organs, the muscles, and other body parts are developing into a completely different creature. When the time comes for the adult to appear, which can take from days up to years depending on the species, it will fight its way from the chrysalis or cocoon and what emerges is the adult.
Butterflies and bees goes through complete metamorphosis.
