We are only beginning to learn from nature and shift our design approaches towards these that emerged in natural evolution — says Piotr Wasylczyk, head of
the Photonic Nanostructure Facility at the Faculty of Physics of the University of Warsaw, Poland, who led the project.
The insects owe their brilliant looks to
photonic nanostructures — crystalline structures in their wings that reflect light and repeat on the order of every few nanometers — and now scientists think that they have figured out how these structures create such vivid colors.
