L. Augustus Weevils Appear the Same Shade of Green from Every Angle

Lamprocyphus augustus weevils have exoskeletons made of chitin scales, which have the same molecular arrangement as carbon molecules in diamonds. The arrangement manipulates light, causing the weevils to appear the same shade of green from every angle.

Defense/Stability:: Light control

Other

Chitin scales have been used to develop optical computer chips.
