Blue Morpho Butterfly Wing (reflected light)
The colors of the Blue Morpho's wing are generated by nanometer-sized structures on the wing's scales. In this image, light reflected from the scales creates the Morpho's characteristic iridescent blue color.
The Blue Morpho is common in Central and South America and known for its bright blue wings. However, these iridescent colors are created not by pigments in the wing tissues but instead by the way light interacts with nanometer-sized structures on the Morpho's wing scales. This effect is being studied as a model in the development of new fabrics, dye-free paints, and anti-counterfeit technologies for currency.
