Scientists Discover Secret To Butterfly’s Invisible Wings
An invisible butterfly might sound like something from a fairytale, but there are butterflies with wings as transparent as panes of glass.
The reason that their wings are transparent is because they barely reflect any light. A wide spectrum of light—from infrared to visible to ultraviolet—travels straight through the wing tissue. The property of the wing tissue that produces the butterfly’s transparency seems to go against nature’s instinct. The nanostructures on the surface of the butterfly’s wings are completely random, researchers report in Nature Communications. They seem to be scattered onto the wing surface with no regard for regular size or structured distribution.
