Butterflies are beautiful, flying insects with large scaly wings. Like all insects, they have six jointed legs, 3 body parts, a pair of antennae, compound eyes, and an exoskeleton. The three body parts are the head, the chest and the tail end.
The butterfly's body is covered by tiny sensory hairs. The four wings and the six legs of the butterfly are attached to the thorax. The thorax contains the muscles that make the legs and wings move.
Some scientists believe that the flap of a butterfly's wings, can cause a hurricane on the other side of the world. This theory is called 'The Butterfly-effect'.
