Final answer:
Butterflies and moths have common attributes and undergo complete metamorphosis. They differ in physical appearance, with butterflies having slender bodies, thin antennae, and brightly colored wings, while moths have plump bodies, feathery antennae, and dull-colored wings.
Step-by-step explanation:
Butterflies and moths have several common attributes. They both belong to the insect order Lepidoptera, which means their wings are covered in tiny scales. They undergo complete metamorphosis, meaning they go through four distinct life stages: egg, larva (caterpillar), pupa (chrysalis or cocoon), and adult.
However, butterflies and moths differ in terms of physical appearance. Butterflies typically have slender bodies, thin antennae with a knob or hook at the end, and brightly colored wings. Their wings are usually held upright when at rest. Moths, on the other hand, have plump bodies, feathery or comb-like antennae (males), and dull-colored wings. Moths often hold their wings flat or folded when at rest.
