On the playground
  • Steven and Sally were bored at home so they
    decided to go to the playground. They took a taxi
    to go there. When they finally reached the
    playground, they found their friends sitting in
    the grass and talking. Steven and Sally sat down
    and looked around. Steven found in the grass a
    small branch with a few green leaves. Suddenly he
    spotted a tiny yellow round object on a leaf.
    What is this? An egg? Is it a butterfly egg? They
    were so excited that they found a butterfly egg!
    They put the egg in a tissue paper and went back
    home. Where should they put the egg?

On a nice green leaf
On the chair

On the chair
  • It seems that it is not very well. It rocks.
    Something is wrong here. We have to call our
    parents to fix the egg to the chair surface.
    Phew! Now everything seems fine. Here we have a
    nice small egg. Oh no! Its breaking. Will it
    hatch? Man! A nice small caterpillar is coming
    out! Oh, we forgot. It needs food! But there is
    no food on the chair. Steven and Sally ask you
    will this caterpillar live without any food?
  • No, certainly not! So go back because you
    selected the wrong option. Click here to go back.

On the leaf
  • It lies very comfortable on the leaf. CRUNCH,
    CRUNCH! It seems that it is coming out. Thank you
    for helping us to make a good choice where to put
    it! Steven and Sally say thanks to you. Now its
    hatching. Look! A nice little caterpillar is
    coming out! It is all yellow and black and it
    looks like a squiggly stick! We should give it
    some food. What kind of food should we feed our
    caterpillar?

More green leaves
Seeds

Seeds
  • CRUNCH! CRUNCH! No, its too hardour caterpillar
    is hungry but there is no suitable food to eat.
  • It is restless in the chair. Now it rocks
    fiercely. BUUUUUU! Then it calms down and doesnt
    move anymore. Dont panic, we can get another
    egg. Dont think that its your fault . Well
    invite you next time when we have another egg!
    Now click here to go back.

More Green Leaves
  • Yum! Yum! It grows and grows. We have to give it
    more food. RUNCH! CRUNCH! Look! It is eating the
    food. It is much bigger now but still so hungry.
    We have to give it even more food. MMMMMMMMM.Day
    by day it is eating and growing. It is getting
    bigger and bigger. What an amazing creature.
    After having pounds of green leaves in two weeks,
    it is a huge caterpillar! It is looking for a
    safe place to turn into a Pupa! Choose the one of
    two options. Thank you for helping Steven and
    Sally!

A plant with branches
A nice soft cushion

A nice soft cushion
  • Oops, we made a mistake. The caterpillar cant
    turn into a pupa in a soft place, neither can it
    hang on a cushion! How could it live? Ask
    yourself can a pupa live in a soft place? No!
    Click here to go back because you selected the
    wrong option.

A plant with branches
Yeah! It is a pupa now! Try to think what the
pupa might want to happen now. Maybe it wants to
turn into a butterfly faster? Or to get married?
What do you think? Have a deep think Well,
we dont know. Anyway, dont give food to the
pupa. A pupa doesn't eat food. Talking about
food, lets eat some sandwiches and watch.
One whole week passed! Look! It starts to turn
into a butterfly or a moth! Watch. POP! It is
a butterfly! Isnt it surprising! Well. Its
time to let him go, because he belongs to the
nature! Thank you for helping Steven and Sally!
Bye!

Lifecycle of a butterflyInformation page 1
Butterfly eggs - Female butterfly lays a great
number of eggs. She puts the eggs on a leaf and
tries to hide them. When the caterpillar is
hatched, it can eat the leaves. Butterfly eggs
are round or oval. Their color could be white,
green, or yellow . Click here to go back to the
story.
Caterpillar - The caterpillar is the 2nd stage in
the butterfly life cycle. In this stage the
caterpillar eats a lot of food. It will not eat
food when it is in a Pupa stage, so it eats a lot
now. This stage lasts from two to four weeks. It
also grows very fast. Click here to go back to
the story

Lifecycle of a butterflyInformation page 2
  • Pupa - In the pupa stage a caterpillar is inside
    a chrysalis. It does not eat anymore. The pupa
    stage can take a few days or even several months.
    Some butterflies spend the whole winter in pupa
    and come out in spring. Some caterpillars like
    silkworm spin a silk cocoon to protect the pupa.

Butterfly - When the adult comes out from the
chrysalis, its wings are wrinkled and wet. The
butterfly pumps the fluid from his abdomen into
his wings to inflate them. When his wings dry up
he is ready to fly. Click here to go back to the
