The iridescence common to these beetles is not due to pigments in the exoskeleton, but instead is caused by structural coloration, in which microscopic texture in their cuticle selectively reflects specific frequencies of light in particular directions. Physicists call these structures photonic crystals, an example of so-called “photonic band gap materials,” meaning they block out certain frequencies of light and let through others.
