Clear-wingedday-flying moth
Irian-JayaIndonesia
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 cylinderson the wing surfaces.
Purpose ? • (1) Anti-reflection coating • (2) Superhydrophobicity
Clear wings surface structureClear wings surface structure
Natural superhydrophobicityNatural superhydrophobicity
The wings achieve alow light reflectanceAND hydrophobic (self-cleaning) properties with the same optimized structure
