Final answer:
Butterflies are insects that go through complete metamorphosis and have fully-formed wings. They lay their eggs on specific plants and exhibit various patterns and colors on their wings.
Step-by-step explanation:
Butterflies are insects that undergo complete metamorphosis, starting as eggs and progressing through larval stages (caterpillars) before becoming fully-formed adults. The adult butterflies have fully-formed wings that they use for flight. They often lay their eggs on specific plants to ensure food supply for the caterpillars. Butterflies also exhibit different patterns and colors on their wings, which serve various functions including camouflage and attracting mates.
