Butterflies are insects in the macrolepidoptera clade Rhopalocera from the order Lepidoptera, which also includes moths. Butterflies are beautiful, flying insects with large scaly wings. Just like all the insects, even butterflies have six jointed legs, three body parts, a pair of antennae, compound eyes, and an exoskeleton. As the butterfly fact and opinion, three parts are the head, thorax, and abdomen. There are several facts about butterflies, just like moths are insects and the caterpillar is the larval form of a butterfly. Adult butterflies have large, often brightly colored wings, and conspicuous, fluttering flight. Adult butterflies are an important source of food for other animals such as bats and birds.
