The ladybug is also known as the ladybird, and more correctly known as the ladybeetle. The insect goes through the four stages of metamorphosis, hatching from an egg to become a voracious larva, then forming a pupa from which the colorful ladybug emerges. Ladybug eggs are attached to leaves of plants infested by aphids, which provide a ready food source for the hungry larva. After molting four times, it enters the pupa stage.
