Abstract

Optical and electron microscopies reveal complexity in the multilayered chiral coatings that produce green metallic-like reflections from manuka (scarab) beetles. In particular the reflectors are shown to have the form of small concave pits and troughs that are filled with contouring chiral material. Each chiral micro-reflector presents a range of pitch and tilt to an incident beam of light. The presentation attempts to relate these physical properties to optical properties such as spectral reflectance, angle of spread and perceived color of the beetles.
