Biologists believe this is an important evolutionary step that helps Glasswing butterflies avoid being hunted by enemies, especially birds.

The Glasswing Butterfly (Greta Oto) is famous for its crystal- clear wings , which have attracted the attention of scientists. 

Recently, scientists have discovered that the random nanostructure on the surface of their wings is the reason why the wings appear “invisible”.

 When light shines on them, most of the light rays pass through this structure, creating a transparent effect. 

Dr. Radwanul Hasan Siddique, who discovered this effect, said that this is a rare phenomenon in nature and that biological structures are usually highly systematic. 

However, the wing structure of the Glasswing Butterfly is completely chaotic, helping them achieve this special “invisible” effect. 

Biologists believe that this is an important evolutionary step that helps Glasswing butterflies avoid being hunted by enemies, especially birds. 

At the same time, this discovery also opens up a new direction for nanotechnology, with the ability to create “random” surfaces that are transparent, waterproof and self-cleaning, similar to the wing structure of the Glasswing butterfly.

This research has been published in the prestigious scientific journal Nature Communication and promises to have many applications in the future.
