The butterfly is one of the amazing features of nature. Unlike other creatures, the lifecycle of the butterfly has four distinct phases. In the first phase, a butterfly lays eggs. The eggs of each butterfly species vary in form, size, and texture but nearly constant colour. And the time required for these eggs to hatch is between 3-5 days.
In the second stage, a caterpillar emerges from an egg. The caterpillars shed their skin while grown i.e., for 3-4 weeks. Next comes the cocoon stage. In this stage, the caterpillar is known as a pupa. Several changes occur in this stage and this stage lasts up to a week.
After the development, the cocoon opens and out comes a butterfly, which is the butterfly. Usually, butterflies come in several shapes and sizes. However, the lifespan of a butterfly varies between one day and one year.
