Insects are cold-blooded. They have no lungs, but small openings on their bodies. Most insects go through a life cycle called Metamorphosis. Most insects go through 4 stages in their lives. The larvae are called wigglers.
ANTS live in a large group called a colony .
BEES are the only insects that make food for man . After the larva has grown , it makes a hard shell around itself. Now it is called a pupa . It changes inside this shell. When the shell burst open , a full-grown fly comes out.
