Entimus imperialis’ photonic polycrystal

Scales covering the elytra of the Brazilian diamond beetle display iridescent photonic polycrystals. The iridescence arises from light interference within the optical structures that constitute the scales. [Honorable Mention 2016 After Image photo contest.]
