Butterfly wing patterns may trick predators with motion illusions

Butterfly wing patterns may trick predators by utilizing motion illusions. These contrasting patterns create misleading motion signals, which make it significantly harder for predators to accurately judge the butterfly's speed and direction during flight. By distorting the visual perception of the attacker, these biological designs serve as a defense mechanism. This phenomenon demonstrates how specific visual arrangements on wings can effectively deceive predators, increasing the survival chances of the butterflies through visual disorientation.
