Butterflies are insects undergo a complete methamorphosis during their life cyrcle. They are born as eggs that hatch into larvae and then grow into pupas, before transforming into adults which are butterflies.Adult female butterflies lay many almost-invisible eggs simulataneously on plants. These plants, later, will become a source food for the hatching eggs, called larvae. At the stage of larvae, the hatching eggs do not look like butterflies. The larvae of butterflies are called caterpillars. The only thing caterpillars do is eat. The food they eat will be stored and used when they become butterflies. During their growth before turning into pupas called chrysalises, they shed skin 4 to 5 times. When they are fully grown, they stop eating ant turn into pupas, hanging under branches, leaver or other hidden areas. inside the pupas, the cells of caterpillars turn into parts of butterflies’ bodies. When the caterpillars come out their pupas, they have already transformed into butterflies. They have compound eyes and long antennae, and legs and wings. At the final stage of their life cycle, the jobs of butterflies are mating, and laying eggs to become the next caterpillars. “adult female butterflies lay many almost-invisible eggs at once on plants.” The word ‘invisible’ means ……..
