There are many different things in nature that are beautifully patterned.
Butterflies are one typical example.
It is easy to see the patterns on a Monarch wing, or a Red Admiral , but there are many more beautiful patterns that can be seen with the help of a magnifier. The scales and hairs on a butterfly wing are responsible for the colors and patterns that we see. Some of the color is caused by pigments. Blue and green is a rare pigment in butterflies and moths although a common color of some butterfly wings. These colors are typically created by the microstructure of the hairs and scales which refract light to produce these colors and a metallic and iridescent effect, which seems to make the wings shimmer in the light.
