The butterfly life cycle has four stages. It will undergo complete metamorphosis, or in other words, a complete change of body form. They begin life as a larva hatched from an egg, pupate in the chrysalis state to emerge as a butterfly, looking nothing like their larval state.
The hard shell, chorion, which protects the embryo is lined with a waxy layer that prevents dehydration. It is nutrient rich and is often the first meal for the newly hatched larva. A small opening in the center of a complexly patterned area on the egg, called the micropyle, allows sperm to enter the egg for fertilization while inside the female. egg has a spherical, cylindrical, or ovate shape and varies in color, texture, and size depending on the species.
