We discuss the use of Mueller matrices for characterizing reflecting properties beetles, including matching patterns significant elements to specific cuticular architectures. In case illumination by natural light, parameters reflected light are related first column matrix. The green and red beetle Stephanorrhina guttata is shown be a narrowband polarization-preserving reflector apart from depolarizing white patches, Calloodes grayanus left-circular reflector, gold Anoplognathus parvulus behaves as broadband reflector. Comparison experimental simulated confirms that reflectors analogs all-dielectric thin-film reflectors. However, Chrysina resplendens, which was formerly known Plusiotis resplendens reflects both right-handed left-handed represented an ensemble laterally incoherent chiral
