Abstract: Among the natural white colored photonics structures, a bio-system has become of great interest in the field of disordered optical media: The scale of the white beetle Chyphochilus. Despite its low thickness, on average 7 ┬Ám, and low refractive index, this beetle exhibits extreme high brightness and unique whiteness. These properties arise from the interaction of light with a complex network of chitin nano filaments embedded in the interior of the scales. As it
