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.
Insects and Metamorphosis
Department of Mathematics and Science
What are two types of metamorphosis?
1. Incomplete 2. Complete
How are these two types alike?How are they different?
