| Popis: | The dazzling iridescence seen in some hummingbirds1 and tropical butterflies2 arises from natural optical phenomena, the brightest of which originate in nanoscale structures that produce ultra-high reflectivity and narrow-band spectral purity3. Here we investigate the coloration of male Ancyluris meliboeus Fabricius butterflies4, which have patches of unusual microstructure on their ventral wing scales. We find that this highly tilted, multilayered arrangement produces a bright iridescence of broad wavelength range and generates a strong flicker contrast from minimal wing movement. |
