2. The Butterfly Life Cycle
Stage One: Egg Stage
Stage Two: Larva Stage
Stage Three: Pupa Stage
Stage Four: Adult Butterfly Stage

3. Stage One: The Egg Stage
Eggs are laid by the female on a foodplant
They are abandoned by the parent
Around five days later, a tiny, wormlike creature will hatch

4. Stage Two: The Caterpillar Stage
The egg hatches into a tiny larva, called a caterpillar
The caterpillar has biting jaws and legs
The caterpillar eats and grows a tremendous amount
The caterpillar sheds its skin in order to grow

5. Stage Three: The Pupa Stage
The caterpillar attaches itself to twig and forms a hard outer shell
Inside the pupa, or chrysalis, the caterpillar changes into a butterfly
Pupas are often camouflaged to hide from predators
This process usually takes about two to three weeks

6. Stage Four: The Adult Butterfly Stage
The butterfly is ready to emerge when the pupa skin is translucent, showing the coloring of the wings beneath
The pupa splits and the limp, damp butterfly emerges
A little warming in the sun and the butterfly is ready to fly and mate
The adult butterfly only lives for a short time
They cannot eat, they only drink
The adult female butterfly lays eggs that have been fertilized by the adult male butterfly.
The Butterfly Life Cycle starts all over!

7. The Frog Life Cycle Stage One: Egg Stage Stage Two: Tadpole Stage
Stage Three: Froglet Stage
Stage Four: Adult Frog Stage

8. Stage One: The Egg Stage
A female frog lays eggs in water
The male frog fertilizes the eggs as soon as the female lays the eggs
This large bunch of frog eggs is called frog spawn
A large spawn of eggs is laid because many of the eggs do not survive and grow into adult frogs
The eggs will hatch between 6-21 days of being fertilized

9. Stage Two: The Tadpole Stage
A tadpole wriggles out of each egg
At first, the tadpole breathes and moves like a fish
The tadpole has gills and a long tail
After five weeks, the gills disappear and the tadpole develops lungs
By seven weeks, the tadpole eats insects and plants
Legs begin to sprout and arms grow

10. Stage Three: The Froglet Stage
By ten to eleven weeks, the front legs have appeared
At twelve to fourteen weeks, the tail disappears
The tiny froglet can leave the water
The froglet is almost a mature frog, about 2-4 months old
The froglet still has some of its tail

11. Stage Four: The Adult Frog Stage
The tail has disappeared
An adult frog may live up to three years
Adult frogs catch and eat insects with their long sticky tongue
They can also eat small fish and worms
Adult frogs hibernate during winter
The adult female frog lays eggs
The adult male frog fertilizes the eggs
The frog life cycle starts all over!
