Wasps use poison stings to fight off predators. Other insects wear special armor. A few insects, like the stink bug, spray stinky liquids at their enemies. Many insects have colors that blend with the places they live. This is called camouflage.
All insects hatch from eggs.
As they grow, they get bigger and begin to look more like their parents. The change the insects go through from egg to adult is called metamorphosis. There are different kinds of metamorphosis. Some insects change by just growing bigger. Others grow wings.
