The life cycle of a frog

Life cycle
Most insects, such as beetles, wasps, and flies, go through complete metamorphosis. They begin life as an egg that hatches to a larva. The larva eats, grows, and sheds, then turns into a pupa in which chemical changes take place. The final stage is changing into the adult insect, which is able to reproduce. In more primitive insects, such as grasshoppers and stick insects, another type of development is used. This process is called incomplete metamorphosis where the insect hatches from the egg as a miniature version of the adult. The insect continues to grow, and every time it molts it gets larger until it reaches adulthood
