Zebra-striped cows repel 50% more biting flies, suggesting patterns evolved as insect deterrents

catracalivre.com.br (Portuguese)

Painting cows with zebra stripes reduced biting flies by 50%, supporting the theory that zebra patterns deter insects. The experiment involved Japanese Black cows treated with non-toxic paint. This suggests zebra coloration evolved as a natural insect repellent, not for camouflage or heat protection. This finding could offer a less chemical-dependent method for pest control in livestock, improving animal welfare and potentially reducing production costs.
