## Butterfly Wings Create Optical Illusions
Optical illusions aren't just for internet entertainment new research suggests butterfly wing patterns help avoid predators.
## 1,000 Frames Per Second Recording
Researchers from England's University of Essex and University of Exeter recorded five butterfly species at 1,057 frames per second.
## Bird Vision Model Analysis
The team fed footage through a bird-vision computer model to compare butterfly movement with actual motion.
## Butterfly Wing Illusion Effect
Wing patterns create a barber pole illusion making birds miss butterflies or hit less delicate parts.
## Pattern Variations Across Species
The researchers studied seven patterns across five species including male-female differences in two species.
## Computer-Generated Patterns
Computer models evolved 50,000 wing patterns finding ones very similar to actual butterfly species.
## Research Published in Nature
The research was published on September 30 in the journal Nature after peer review.
## Key takeaway

Butterfly wing patterns create optical illusions that help birds miss them.
