Many morpho butterflies are colored in metallic, shimmering shades of blues and greens. These colors are not a result of pigmentation but are an example of iridescence through structural coloration: the microscopic scales covering the Morpho’s wings reflect incident light repeatedly at successive layers, leading to interference effects that depend on both wavelength and angle of incidence/observance.

Technical application:

“painting” without pigments, thermal sensors

Bionic application:
