The sun shines on

wildflowers.

A tiny egg hides

under a leaf.

The egg splits open.

A caterpillar crawls out.

Credit 1

The caterpillar

is very hungry.

She eats her eggshell.

Munch!

Credit 2

She grows bigger.

Leaves are yummy.

Crunch!

Other insects

join the feast.

Red aphids (AY-fids)

slurp sap.

Bees slurp nectar.

Credit 3

Spiders spin webs

to trap meals.

The caterpillar grows

even bigger.

Soon she will be too big

for her own skin!

To keep growing,

she must shed her skin.

This is called molting.

Credit 4

Her old skin splits open.

She wiggles out.

She has a new

set of stripes.

She is always hungry.

Her body is

done growing.

She has molted

four times.

She spits up a blob

of sticky stuff.

She sticks to it

and hangs upside down.

The caterpillar molts

one last time.

She has formed a sac

around herself.

Credit 5

The sac is called a

chrysalis (KRISS-uh-liss).

Many changes are

going on inside.

The caterpillar is

changing into a butterfly!

Now the chrysalis is

almost see-through.

After ten days or so,

the sac opens.

A butterfly pops out!

But she is too weak to fly.

She holds on to the sac.

She pumps fluid

into her new wings.

Her wings dry in the sun.

Now the butterfly flies

and looks for food.

She has not eaten

in two weeks!

Credit 6

The butterfly flies

from flower to flower.

She unrolls her tongue.

It is like a straw.

Credit 7

She sips sweet nectar.

Soon she finds

a winter home

with other butterflies.

It is time to mate.

Our little butterfly

lays her eggs

under the leaf

of a plant.

A few days later,

a caterpillar

eats its way

out of its shell.

Credit 8

The little caterpillar

is very hungry.

Can you guess what

happens next?
