Butterfly

Butterfly is my favorite animal also. so, How does a caterpillar become a butterfly?
During her life time a female butterfly can lay from 100 to several thousand eggs. She is very careful to lay these eggs near the kind of plant that will be useful to her offspring later.these eggs will hatch into tiny, wormlike grubs called" catepillar larvae" which begin to feed and grow immediately.They will shed their skin overal times. When the caterpilliar feels it is time for a change, it spins a little button of silk to which it clings. It lands head down and sheds its caterpillar skin. It then appears as a pupa or chrysalis. The pupa or chrysalis may sleep for some weeks . During this time it is undergoing a change, so that when it emerges from its chrysalid skin, it is a butterfly. It will spread its wings so that tahy can dry and become firm before it will attempt to fly
