The beetle Entimus imperialis forms photonic crystals with a bicontinuous cubic structure of the diamond type in cuticular scales that show brilliant colors within well‐defined domains. On page 3615 , H.‐O. Fabritius and co‐workers report how the beetles tune the structural parameters and composition of these biological photonic crystals to achieve opposite extremes for their optical properties: the brightest colors possible or a colorless appearance.
