The first time I thank the brothers 
Understanding butterflies for us are very familiar. Butterflies are colorful insects with large triangular wings. The scientific name of the butterfly group comes from small scales that fill its wings. These scales are very soft, so easily fall off when the butterfly wings are held carelessly by human hands. The ability to fly is clearly the key to the success of such a large insect. Flying animals can avoid many predators, find food and married couples, butterfly wings appear to be common, but with special photographic technology, it can be seen that the butterfly wings bend and twist as they move up and down. This twisting and twisting motion pushes the air backward, moving the butterfly body forward so that the butterflies can fly.
