Insects | Basic Biology

During each metamorphosis, the insect sheds its old exoskeleton and the external body form gradually changes until reaching its final adult form. The final change for many species is often dramatic as the wings of the insect become fully developed. A well-known example of this is the metamorphosis of a caterpillar into a butterfly.
