Blue Morpho Butterfly Wing Ridges

Blue Morpho Butterfly Wing Ridges
This scanning electron microscope image shows ridges on a Blue Morpho Butterfly wing scale. These ridges contain nanoscale structures that reflect light to create the Morpho's iridescent colors. 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.
