  5. Go over complete and incomplete metamorphosis.
    • Complete Metamorphosis
      • 4 stages
        • egg [unborn]
        • larva [usually look like worms]
        • pupa [inactive, usually camouflaged]
        • adult [usually have wings]

  6. Go over Simple (Incomplete) Metamorphosis - About 12% of all insects, as well as spiders, go through incomplete metamorphosis. This group includes dragonflies, grasshoppers and cockroaches
    • 4 stages
      • egg [unborn]
      • nymph [often look like adults without wings]
      • adult [usually have wings]
