Characteristics of Insects

• Insects are small animals with a head, a thorax, an abdomen, and six legs. • All insects start their lives as eggs. • These eggs can be different colors, shapes,

and sizes.• All insects go through metamorphosis after

birth.

Life Cycles of Insects

Animals that change their appearance during growth undergo metamorphosis. That's just a long word meaning "to change shape.“ The change that occurs when an insect egg hatches and grows into an adult is called metamorphosis, meaning to change in form.
