Living Light: Uniting biology and photonics – A memorial meeting in honour of Prof Jean-Pol Vigneron Bouligand Structures Underlie Circularly Polarized Iridescence of Scarab Beetles: A Closer View


The iridescent metallic green beetle, Chrysina gloriosa, selectively reflects left circularly polarized light, and exhibits iridescence. The exoskeleton of C. gloriosa is decorated by a polygonal texture: hexagonal cells (~10 micron) coexist with pentagons and heptagons. We find that the fraction of pentagons and heptagons computed using Voronoi analysis… (More)
