A caterpillar turning into a butterfly

Detailed explanation-1: -A caterpillar changing into a butterfly is NOT an example of evolution. Evolution is the change that requires several generations for occurrence. Metamorphosis is defined as the change in animals that appears in the form of body change.
Detailed explanation-2: -Non-genetic changes are not an example of evolution. An increase in muscle mass due to exercise/diet cannot be passed on to the generations. Hence, it is not an example of evolution.
Detailed explanation-3: -The colorful canvas of the butterfly wing is an exceptional example of evolutionary innovation and adaptation. Compared with their forebears, whose wings wore patterns of black, brown, and gray, the Lepidoptera (butterflies and moths) evolved a more varied palette of pigmentation.
Detailed explanation-4: -Bees evolved some 125 million years ago, and the plants produced nectar to secure them as pollinators. Because moths had already developed strawlike mouthparts, one group was able to exploit the novel food source, and evolved into butterflies.
