Butterflies and their cousins, moths, are the only insects with scales—their wings are covered with them. These scales are responsible for butterflies’ amazing colors, like the brilliant hue of the blue morpho. That dazzling blue isn’t the result of pigment—it’s all how the light hits their prismatic scales.
Butterflies’ color is even responsible for their name. A common European butterfly, the yellow brimstone, is a bright, sunny color. It’s believed that people once referred to it as a “butter-colored fly,” which got shortened to “butterfly.” This spring, see how many different colors of butterflies you can find!
