These Beetles Are Bright and Shiny… For Camouflage

The video explores the concept of iridescence, a structural color phenomenon seen in nature, particularly in jewel beetles. Unlike pigment-based colors, iridescence results from light interacting with microscopic structures. A study showed that iridescent beetles might use their colors for camouflage rather than display. Experiments with model beetles revealed that iridescent and black beetles were less likely to be eaten by predators, suggesting that their changing colors provide dynamic disruptive camouflage. This makes it harder for predators to focus on them, offering a survival advantage.
