| 🟤When resting, morphos fold their wings up, showing their dark, earth-toned undersides. The brown, yellow and black colors are generated by pigments. 💙The top, bright blue side of a morpho’s wings have tiny scales with ridges, or nanostructures, that affect how the wings refract light – similar to a prism. 💡When light hits these ridges, a phenomenon called constructive interference comes into play. The spacing between the ridges, which look like little Christmas trees, perfectly reinforces specific wavelengths, while canceling out others, causing our eyes to perceive shimmering blue on the morpho’s wings. |
