Butterflies are known as flying flowers because of their colorful bodies and wings. They come under the category of "insect". A butterfly has six legs, four wings, and two antennae. The thin, delicate lines that make them colorful are called scales. Most butterflies are harmless. You can find butterflies everywhere in the world, except Antarctica. Butterflies are also an important part of nature because they make the flowers bloom by cross pollination. Cross-pollination means, pollinating a flower or plant with pollen from another flower or plant.
