A unique butterfly breeding experiment gave researchers an opportunity to study the physical and genetic changes underlying the evolution of structural color, responsible for butterflies' iridescent ...

A closer look at seemingly drab, transparent insect wings has revealed realms of previously unappreciated color, visible to the naked eye yet overlooked for centuries. Until now, the wing colors of ...

“The brilliant iridescent colors of hummingbirds are … structural colors, not pigment, which means they are reflected by microscopic structural features of the feather surface … composed of layers of ...
