Summary

Story summary

British researchers demonstrated that butterfly wing patterns create visual motion illusions that misdirect predator attacks.
The University of Exeter and the University of Essex studied about 400 European butterfly species.
High-speed cameras captured wing-pattern motion at over 1,000 frames per second.
Simulated predators on a touchscreen struggled to catch virtual butterflies, matching computer-evolved wing designs.
