What is reproduction?
A process by
which living things produce more of their kinds.
Why do animals
Animals reproduce so that their races
do not die out.
How do animals
By laying eggs
By giving birth to babies
The life cycle of egg laying
animals consist of 2, 3 or 4 stages.
Butterflies belong to group Insecta
and lay eggs. They pass through four stages in their life cycle.
Egg > Caterpillar > Pupa > Butterfly.
Now let's learn about the different
life stages of a butterfly.
The Egg stage
The eggs of butterfly are tiny and
have a variety of shapes. The female butterfly lays the eggs on the leaves
of the plants. After 6-7 days a worm like creature hatches out of the egg
which is light green or yellow in colour.
The Larva stage
It is tiny worm like known as baby
caterpillar but does not undergo moulting (it's the process of shedding
of skin several times before growing into an adult).
This is the active stage. The larva
eats leaves and grows to a tremendous amount. This fully grown larva is
called a caterpillar which has six real legs and a number of extra prolegs.It
is the young one of a butterfly and does not resemble its parents.
The Pupa stage
This is called the resting stage.
The caterpillar first spins a cocoon around its body and also fastens itself
to a plant with a silk thread. The caterpillar which is inside the pupa
changes into a butterfly. Generally pupas camouflage themselves to hide
In this stage the baby butterfly
emerges from the pupa and soon is transformed into an adult butterfly.
Insects and butterflies change in
form in their development from egg to adult. The different instars are
not alike, this process is called metamorphosis
In a nutshell we can say that a Butterfly
passes through four stages in its life cycle. Usually it lays eggs on a
leaf. When the eggs hatch a small larva emerges and crawls out. This larva
of a butterfly is called a caterpillar which starts eating the leaf and
grows This is the active stage. During its life it moults a few times.
Each time it becomes bigger. Soon it changes into a pupa. This pupa may
be hanging on the plant in a small loop of silk. And after a few weeks
the pupa turns into a beautiful adult butterfly.
Below is given the complete metamorphosis
stage in which the wings develop internally during the larval stage. The
larval stage looks very different from the adult stage. There is a pupal
stage which usually is inactive between the last larval stage and the adult
