First is the egg stage. The female butterfly will look for a plant or leaf on which to lay her eggs. Each species of butterfly has specific plants that they lay their eggs on. The eggs are very small, usually no bigger than the head of a pin. They are very delicate and often difficult to spot. Once they have been laid, they will typically hatch in a few days.
The next stage is the larva stage, better known as the caterpillar. When the eggs hatch, the newborn caterpillars emerge. They are very small and all that can be seen are their eyes and a few other features. Over the next few days and weeks the caterpillars will continue to feed and grow, shedding their skin several times, until they have reached a certain size and are ready to proceed to the next stage.
The pupa stage is when the caterpillar develops into a pupa, or chrysalis. During this stage, the caterpillar is undergoing dramatic transformation. The pupa is relatively immobile and protected by a hard shell. During this stage, the organs and interior of the caterpillar are completely remade into the body of a butterfly. The pupa will stay in the shell for a certain amount of time, depending on the species, before finally emerging as a butterfly.
Finally, in the adult stage, the butterfly breaks out of the pupa and can now fly freely. The adult butterfly’s wings are usually colorful and vibrant, used as a warning signal to predators. The adult butterflies can now look for food and lay eggs of their own. Depending on the species, the butterfly may live anywhere from a few days to a few months in its adult stage.
The life cycle of a butterfly is a remarkable example of the power of nature and the cycle of life and death. From the moment it emerges from its egg, to its adult stage when it takes flight, a butterfly's lifecycle is something to behold.
