“…Nevertheless, we tested for any contribution of epicuticular wax to the wing membrane reflectance. We manually removed the scales by softly brushing a transparent wing region with a paintbrush (electronic supplementary material, figure S3), followed by plasma cleaning to remove surface hydrocarbons (electronic supplementary material, figure S4) [ 30 ]. Then, we measured the reflectance of the treated wing membrane.…”

“…To remove surface hydrocarbons, we cut the wing into small pieces, manually removed the scales from the transparent region, and placed them in a plasma cleaner. Ultraviolet light generated in the plasma breaks most organic bonds of hydrocarbons [ 30 ]. Moreover, the radical oxygen species generated react with the broken-down organic contaminants to form mainly water and carbon dioxide that are continuously removed from the chamber.…”

Optical transparency is rare in terrestrial organisms, and often originates through loss of pigmentation and reduction in scattering. The coloured wings of some butterflies and moths have repeatedly evolved transparency, offering examples of how they function optically and biologically. Because pigments are primarily localized in the scales that cover a colourless wing membrane, transparency has often evolved through the complete loss of scales or radical modification of their shape. Whereas bristle-like scales have been well documented in glasswing butterflies, other scale modifications resulting in transparency remain understudied. The butterfly Phanus vitreus achieves transparency while retaining its scales and exhibiting blue/cyan transparent zones. Here, we investigate the mechanism of wing transparency in P. vitreus by light microscopy, focused ion beam milling, microspectrophotometry and optical modelling. We show that transparency is achieved via loss of pigments and vertical orientation in normal paddle-like scales. These alterations are combined with an anti-reflective nipple array on portions of the wing membrane being more exposed to light. The blueish coloration of the P. vitreus transparent regions is due to the properties of the wing membrane, and local scale nanostructures. We show that scale retention in the transparent patches might be explained by these perpendicular scales having hydrophobic properties.
