Insects are cold blooded and have six legs, three main body parts and an exoskeleton. Insects also lay eggs and many have four wings.Know More
Insects have a hard protective covering called an exoskeleton. Because they lack backbones, they are invertebrates. An insect's body has three major body parts, including a head, thorax and abdomen. Insects can live on land, in the water or both and are cold-blooded creatures that require the sun to warm them. Most insects have antennae that allow them to touch, taste, hear and smell. These antennae help them locate food and sense danger from predators.
Some insects go through a complete metamorphosis, meaning they grow into completely different creatures than they were in their larval stage. Insects that go through this change include butterflies, true flies and beetles. Insects that go through an incomplete metamorphosis look very similar to adults of the same species, only smaller. Cockroaches and grasshoppers go through an incomplete metamorphosis.
