It is known that the structural colors of some beetles originate from multilayer thin-film interference. We investigated such an example, a jewel beetle Chrysochroa fulgidissima, to quantitatively characterize the coloration mechanisms. The essential physical factors of the iridescence were elucidated by careful determinations of the structural parameters, measurements of angle and polarization-dependent reflection spectra, and theoretical modeling of the multilayer system. On the basis of the elucidated coloration mechanisms, we successfully prepared a dielectric thin film structure that reproduces the iridescence of the jewel beetle.
