3. Life Cycle of a Butterfly *Click on picture to find out more
The First Stage: The Egg
The Second Stage: The Larva
The Third Stage: Pupa
The Fourth Stage: Adult Butterfly

4. First Stage: The Egg
Starts life as a very small, round oval, or cylindrical egg
If you look close enough, you can actually see the tiny caterpillar growing inside
Egg shape depends on the type of butterfly that laid the egg
*Click Next for more information

5. First Stage: The Egg The eggs are laid on the leaves of plants
In order to find them, you would have to look very hard at many different leaves

6. Second Stage: The Larva
When the egg hatches, out comes butterfly larva which we call caterpillars
Do not stay in this stage for very long and all they do is eat
Once they eat, they instantly start growing and expanding. Their exoskeleton does not stretch or grow, so they grow by “molting” (shedding outgrown skin) several times
*Click Next for more information

7. Second Stage: The Larva
Once the egg hatches, caterpillars eat the leaf it was born onto because the mother butterfly needs to lay her eggs on the type of leaf the caterpillar will eat-each caterpillar type only likes certain types of leaves.

8. Third Stage: Pupa
When a caterpillar reaches their full length/ weight, they form themselves into a pupa also called a chrysalis
Inside of the pupa, the caterpillar is rapidly changing
*Click Next for more information

9. Third Stage: Pupa Undergo transformation called metamorphosis
Tissue, limbs, and organs all change
*Click on link to view video!!

10. Fourth Stage: Adult Butterfly
When the butterfly first emerges both wings are soft and folded against its body
After it comes out, it will pump blood into the wings in order to get them working and flapping
Within a 3-4 hour period, the butterfly will master flying
*Click Next for more information

11. Fourth Stage: Adult Butterfly
Adult butterflies are constantly on the look out to reproduce
Once this happens, the cycle starts all over again.

13. Antennae
Moveable, segmented organs used for detecting smells at the tips and structures for sensing direction and position.
Antennae are used for the sense of smell and balance.
Butterflies have two segmented antennae with a small club at the end of each.
Larvae (caterpillars) have tiny sensory antennae

14. Thorax Contains flight muscles Anchor point for the legs
Expansion and contraction of muscles causes the wings to rise and fall at rates up to 1,000 beats per second

15. Compound Eye Sensory organs on the head
Good at detecting color and nearby movement
Focus light onto a rhabdome (retina). Then the optic nerve carries this information to insect’s brain
See ultraviolent rays

16. Proboscis Long, straw-like tube used for drinking
When a butterfly finds food, it first unfurls its mouthparts and then zips them together to form a channel.
The proboscis is particularly well adapted for reaching into flowers for nectar and for piercing fruit with its sharp tip.
When a butterfly is not feeding, it keeps its proboscis curled between its palpi (which are a pair of organs located on the front of an adult butterfly face).

17. Head Location of its feeding and sensory structures
Contains brain, 2 compound eyes, proboscis, pharynx (the start of the digestive system), and the point of attachment of its two antennae

18. Legs
At the end of each six legs, all which are attached to the thorax, are taste organs used to find food
Legs touch food, a reflex causes its proboscis to uncoil
This lets the butterfly retrieve and swallow food
Detects and amplifies small vibrations to alert butterfly when animals approach

19. Abdomen
Once the butterfly swallows food, it is digested in organs located in the abdomen
Segmented tail area of an insect (11 segments)
An insect's abdomen contains its heart, Malpighian tubules, and reproductive organs
It is protected by an exoskeleton

20. Hindwing Hind wings are the two lower wings
Closer to the tails and are shaped like fans or seashells
Colors and patterns come from layers of tiny scales. These scales protect wings and provide insulation
Scales on top-brightly colored
Scales underside-camouflage

21. Forewing Two upper wings
Closer to butterfly’s head and are roughly triangular

22. Wing Veins
Once butterfly emerges from the chrysalis, wings have to expand and dry. To do this, it uses its body as a pump and forces fluid trough a series of tube-like veins
As the veins fill with fluid, they slowly stretch the surface of the wings
