Life of Butterfly



The life of a butterfly starts when male and female adult butterflies meet and mate while flying around each other in a meadow for a short span of time. The male adult butterfly then flies away from the female butterfly and the female butterfly finds place to lay her eggs. The female butterfly curves her long body in the direction of a leaf and lays her very tiny eggs on the surface of the leaf during the time of monsoon.
The eggs are made of sticky substance so that they wont fall from the leaf. The young stage known as larva is then developed inside the egg and one caterpillar will hatch out from one egg. The caterpillar grow very quickly, the more it eats the bigger it become in size. Eventually the caterpillar will shed from its first skin and grow a bigger skin. There is no time for caterpillar to sleep because it has to store as much energy as needed to change into butterfly. It is now time for the caterpillar to make chrysalis for butterfly and cocoon for moths. The caterpillar mus find a hard sturdy branch where it can spin silk threads around the branches. It will shed its skin for the last time and a shell will form underneath. This shell will hardens into a protective cover which is called Chrysalis.
The caterpillar turns into a soft,squidy jelly like blob. The caterpillar then change into a beautiful butterfly after few weeks. When the chrysalis turns clear it is the appropriate time for butterfly to take its first flight. Once the butterfly breaks out its wings are wet and crumpled. The butterfly then pumps blood into its wings which will help to dry out and to expand.
This stage doesnot take long time.Once its wings are dry the butterfly is ready to fly away for the search of flowers. Not all butterflies hatch out of thier chrysalis, some spend winter month inside and hatch out in spring time. Most of the butteflies have short span of life about a month so it must find a mate quickly to start new life cycle all over again.
There are several butteflies that have longer lives (upto nine months). For these butterflies, when winter arrives, they will hibernate by findings a safe shelter. Butteflies use the sun to elevate their body temperature.
