  1. Complete and Incomplete Metamorphosis SC.4.L.16.4 Compare and contrast the major stages in the life cycles of Florida plants and animals, such as those that undergo incomplete and complete metamorphosis, and flowering and nonflowering seed-bearing plants.

  2. What is metamorphosis? • Metamorphosis refers to the way that certain organisms develop, grow, and change form. • Metamorphosis actually means "change."

  3. Two Types of Metamorphosis in Insects • Incomplete Metamorphosis • Complete Metamorphosis

  4. INCOMPLETE METAMORPHOSIS Let’s take a closer look at each stage!

  5. 3 STAGES OFINCOMPLETE METAMORPHOSIS • Egg • Nymph • Adult

  6. EGG • A female insect lays eggs. • These eggs are often covered by an egg case which protects the eggs and holds them together.

  7. NYMPH • The eggs hatch into nymphs. • Nymphs looks like small adults, but usually don't have wings. • Insect nymphs eat the same food that the adult insect eats. • Nymphs shed or molt their exoskeletons and replace them with larger ones several times as they grow. • Most nymphs molt 4-8 times.

  8. ADULT • The insects stop molting when they reach their adult size. By this time, they have also grown wings.

  9. What are some animals that undergo incomplete metamorphosis? dragonfly termites grasshopper bush cockroach

  10. COMPLETE METAMORPHOSIS in INSECTS Let’s take a closer look at each stage!

  11. 4 STAGES OFCOMPLETE METAMORPHOSIS • Egg • Larva • Pupa • Adult

  12. EGG • The female lays eggs.

  13. LARVA • Larva hatch from the eggs. • They do not look like adult insects. • They usually have a worm-like shape. • Caterpillars, maggots, and grubs are all just the larval stages of insects. • Larvae molt their skin several times and they grow slightly larger.

  14. PUPA • Larva make cocoons or chrysalises around themselves. • Larva don't eat while they're inside their cocoons or chrysalises. • Their bodies develop into an adult shape with wings, legs, internal organs, etc. • This change takes anywhere from 4 days to many months.

  15. ADULT • Inside the cocoon or chrysalis, the larvae change into adults. • After a period of time, the adult breaks out of the cocoon or chrysalis.

  16. What are some animals that undergo complete metamorphosis? honey bee Emperor Gum moth Painted Lady butterfly ant house fly

  17. What about frogs? • Frogs undergo a different type of METAMORPHOSIS. • From the egg emerges a tadpole, which lives in the water, breathes with gills, and has a tail. • As the tadpole grows, lungs and legs form, and the gills and tail are absorbed into the body. • Finally, the animal leaves the water and lives mainly on land, as a frog.

  18. QUESTION #1 What are the two types of metamorphosis in insects?
