Chrysina resplendens (Cedric Vandenbem) Infrared mirror Green mirror Red mirror Avoiding iridescence More on this : see Cedric Vandenbem
Cocytia dUrvillei (Arctiidae) Clear-winged day-flying moth Irian-Jaya Indonesia There is, in the island of Java, a moth which succeeds in solving an extraordinarily difficult and important problem : antireflection and self-cleaning (see photovoltaic panels, which should not reflect light and keep clean)
Array of upright cylinders on the wing surfaces. Purpose ? (1) Anti-reflection coating (2) Superhydrophobicity Clear wings surface structure
Natural superhydrophobicity The wings achieve a low light reflectance AND hydrophobic (self-cleaning) properties with the same optimized structure
