How many stages of the life cycle does a butterfly have? Butterflies have 4 stages of life: egg, caterpillar, pupa and butterfly. The butterfly starts out its life in an egg, and once it is laid, it eats it for its first meal. Once â¦a caterpillar, it transforms itself into a cocoon, also known as the pupa stage. It stays inside the cocoon for about 85 days.
This means that the butterfly changes completely from its early larval stage, when it is a caterpillar, until the final stage, when it becomes a beautiful and graceful adult butterfly. The butterfly life cycle has four stages: egg, larva, pupa, and adult. The first stage of the butterfly life cycle is the egg or ovum. Butterfly eggs are tiny, vary in color and may be round, cylindrical or oval. The female butterfly attaches the eggs to leaves or stems of plants that will also serve as a suitable food source for the larvae when they hatch.
