Butterfly wing scales. Coloured scanning electron micrograph (SEM) of a scale from the wing of a Ulysses butterfly (Papilio ulysses),showing the photonic crystal structure. The colour of a butterfly's wing can arise either from a pigment contained in the scales or from the actual structure of the scales themselves,as here. Photonic crystals are nanostructures that affect the motion of photons in light,producing a specific colouration | |
