Passage:

The Life Cycle of a Butterfly

Butterflies are some of the most beautiful and fascinating insects in the world. Their life cycle consists of four distinct stages: egg, larva (caterpillar), pupa (chrysalis), and adult butterfly.

The journey begins when a female butterfly lays her eggs on the leaves of a plant. These eggs are often tiny and can vary in shape and color depending on the species. After a few days, the eggs hatch, and tiny caterpillars emerge. This stage is known as the larva stage.

Caterpillars are known for their voracious appetite. They eat continuously, shedding their skin several times as they grow. This process is called molting. The primary goal during this stage is to eat and store energy for the next phase of their life cycle.

Once the caterpillar has grown sufficiently, it forms a pupa, or chrysalis. During this stage, the caterpillar undergoes a remarkable transformation called metamorphosis. Inside the chrysalis, the caterpillar's body is broken down and reorganised into the structure of a butterfly. This stage can last from a few weeks to several months, depending on the species and environmental conditions.

Finally, the adult butterfly emerges from the chrysalis. At first, its wings are soft and crumpled, but after a few hours, they expand and harden, allowing the butterfly to fly. Adult butterflies are known for their vibrant colours and patterns, which can serve various purposes, such as attracting mates or warding off predators.

The lifespan of an adult butterfly can vary greatly. Some species live only for a few days, while others can live for several months. Butterflies play an essential role in the ecosystem as pollinators, helping plants reproduce by transferring pollen from one flower to another.
