2. What are some animals life cycles?
• Different types of animals change in different ways.
• Some animals are born looking like their parents, others are
not, these animals might change shape, size and color as
they grow.
• The way an animal changes with age is apart of its life cycle.
3. Butterflies, moths, beetles, flies and bees have complete metamorphosis. The young (called a larva) is
very different from the adults. It also usually eats different types of food.
4. So, what Life cycle is?
• The changes that happen to an animal during its
life.
• The change in shape, color and size is called “
METAMORPHOSIS”
5. Types of Metamorphosis
• Incomplete metamorphosis
• In which the young looks
like its parents.
• Complete metamorphosis
• The young changes shape
before becoming an adult.
6. Butterfly as an
example on the
complete
metamorphosis:
Butterfly life cycle has four
stages:
1-Adult butterfly
2-eggs
3-larva
4- Pupa
7. Butterfly life cycle
Butterfly grows into an adult through 4 stages :
1) Adults : They are the reproductive stage.
The females of the butterflies lay eggs.
Adult butterflies look very different from the larva.
The one thing they can't do is grow.
* Some species of adult butterflies get energy by feeding on
nectar from flowers but many species don't feed at all.
8. Butterfly life cycle:
• 2) Eggs : Eggs are laid on plants by the adult female
butterfly. These plants will then become the food for the
hatching caterpillars.
9. Butterfly life cycle
3) Larva : This is also called a caterpillar if the insect is a
butterfly or a moth.
• The job of the “caterpillar” is to eat and eat and eat. As the
caterpillar grows it splits its skin and sheds it about 4 or 5
times. Food eaten at this time is stored and used later as an
adult.
10. Butterfly life cycle
4) Pupa: When the caterpillar is full grown and stops eating, it
becomes a pupa. The pupa of butterflies is also called a
chrysalis.
. The pupa of many moths is protected inside a cocoon of silk.
11. Ladybug life cycle
• Females lay their tiny eggs in yellow clusters under a leaf or
stem
• the eggs hatch into alligator-shaped larvae that start
gobbling up tiny worms and a variety of insect eggs.
• Larva eats bugs and grows
• Pupa forms a hard shell. Inside it grows wings.
