The striking coloration of the weevil Lamprocyphus augustus is the result of exoskeleton photonic structures with a diamond‐based lattice. Michael Bartl and co‐workers report on p. 107 on the development of a sol–gel templating method to convert these unique biopolymeric structures into high‐dielectric replicas. Theoretical, structural, and optical studies reveal these bioderived photonic crystals possess a complete bandgap at visible frequencies – the basis for novel optical phenomena based on light localization.
