Butterfly Wing Patterns Create Illusions to Evade Predators

A joint research team, led by the University of Exeter, has discovered that the vibrant stripes and spots on butterflies' wings create optical illusions during flight, causing predators to misjudge their speed and direction. This mechanism helps butterflies evade attacks, solving a long-standing puzzle about their conspicuous yet effective defense. The findings were published in the journal *Nature*.
