“A CIRCULARLY POLARIZING REFLECTOR is formed when birefringent chitin layers are deposited helically … with a periodicity … equal to a wavelength of visible light. Under incident unpolarized white light … polarized coloured light is reflected; the majority of green ruteline scarabs reflect polarized light with a left-handed (anticlockwise) rotation.”
