Surely we are familiar with butterflies because they often we meet around us. being very close to humans sometimes we meet in the yard, flower garden, and inside our house, to know him very easily because he has butterfly wings is not a modified limb, but is an extension of the cuticle. Fluttering wings with several hundred fan speeds per second using muscles is done to bend the shape of the entire cuticle covering the thorax. While the wings are flapping, the wings change the angle, thus generating lift (floating) from flapping up and down. The ability to fly is clearly the key to the success of a butterfly.
When we look at butterflies have their own uniqueness in terms of slim body, the wings are generally bright and attractive, the antenna at the tip enlarged. At rest its wings close and perpendicular to the body so that it is visible is the surface of the lower wing. A butterfly that feeds at night (moths) has a fatter posture, whereas its wings are dull, the antenna is generally plumose type (in the form of chicken feathers) and at rest its wings are open unlike other butterflies, and covering the abdomen so that the visible top surface of the butterfly wing itself. The uniqueness of another butterfly is considered a highly skilled insect in the flight, with the precision of its flight it can avoid the attack of predators who will attack it.
