The wings, head, part of the thorax and abdomen of a butterfly are covered in minute scales, a feature from which the order of Lepidoptera, derives its name. Wing scales form the color and pattern on the wings. Most scales are blade-like, while others forms are more similar to hair. Each scale gives color either by colored pigments that it contains or through the structural colorization that reflects light. Scales also provide insulation and help butterflies glide while in flight, but the most important vivid and distinct patterns provide protection by acting as camouflage.
