These insects either have hemimetabolous development, and undergo an incomplete or partial metamorphosis, or holometabolous development, which undergo a complete metamorphosis, including a pupal or resting stage between the larval and adult forms. In hemimetabolous insects, immature stages are called nymphs.
Metamorphosis is the series of developmental stages insects go through to become adults. Butterflies and moths have four stages of life: egg, larva (the caterpillar stage), pupa (the chrysalis phase in a butterfly's development), and adult.
