2. Two Types of Insect Life Cycles
Complete metamorphosis
Incomplete metamorphosis

3. Complete Metamorphosis
Example of Complete Metamorphosis:
Metamorphosis that involves four stages. The four stages being egg, larva, pupa, and adult. This occurs in insects such as butterflies, beetles, flies, and bees.
The Butterfly

4. The Stages of Complete Metamorphosis
Stage 1- Egg
Stage 3- Pupa
Stage 4- Adult
Stage 2- Larva (Caterpillar)
Size of a pinhead
Caterpillars grow inside the egg for 1-2 weeks.
When the caterpillar is big enough, it will molt its skin and turn into a chrysalis (Pupa)
They stay in the chrysalis for 1-2 weeks
Once they have completely formed, they will come out of the chrysalis
The adult butterfly will only live for 1-2 weeks
Once out of the egg, the caterpillar eats until it sheds its skin
Caterpillars will eat for 3-4 weeks

5. Incomplete Metamorphosis
Example of Incomplete Metamorphosis:
Metamorphosis that only involves three stages. The three stages being egg, nymph, and adult. This occurs in insects such as grasshoppers, ants, and cockroaches.
The Grasshopper

6. The Stages of Incomplete Metamorphosis
Stage 1- Egg
Stage 3- Adult
Stage 2- Nymph
Full grown, takes about 1 month for wings to fully develop
Live fully grown about 2 months
During this stage they undergo five other stages to become an adult
This stage lasts 5-6 weeks
Each pod contains 15 to 25 eggs
The eggs remain in the pod for 10 months
