Colour
The metallic green colouring of the beetle's surface is the reflection of mostly circularly polarised light, typically left circularly polarized light. When viewed through a right circular polariser, they appear to be colourless. Many species of scarab beetles (scarabaeidae) are known to emit typically left circularly polarised light (see Circular polarization in nature).
