         Caterpillar to butterfly

 Statement:

Many butterflies can taste with their feet to find out whether the leaf they sit on is good to lay eggs on to be their caterpillars' food. Read my explanation to find out more.

Eggs:

First, eggs are layed on a safe plant that has leaves that are not too sharp. There are 100-200 eggs that are layed and they look like a new white pearl. There is about 2 or 3 eggs that will survive to be adults only.

Hatching:

The baby caterpillar hatches out of its egg by nibbling the egg. It finds its way out of the egg. Before long, it will eat the rest of its egg for nutrients and then it will eat the leaf.

Shed:

Consequently, it grows and splits its skin about 3 or 4 times. Do you know why it splits its skin? It changes its skinbecause the skin does not grow, isn’t that amazing! We cannot shed our skin.

Building a crysallis/cacoon:

All that caused the caterpillar to make silk; it can stick its head onto the branch and now it can make a belt. It can make itself stick onto a branch ready for the change. It will start to use its spinnerets (which are two things at the front of its mouth) to make a crysallis/cacoon.

Waiting and hatching:

It will now wait for a week or more to hatch out of the crysallis/cacoon. Inside the chrysalis the caterpillar has changed to pupa and it will metamorphisis (change). When it hatches it will then be a butterfly. Its wings are dusty wet; it just came out of its crysallis/cacoon.

Free butterfly:

As a result, the butterfly will suck out all the nectar by using its curly tongue and get the pollen from the flower. The butterfly will carry on doing this until it has eggs.

Final statement:

Now, you know what metamorphisis means if you still do not know the meaning read my explanation writing again.
