Cows painted like zebras attract fewer flies

ClickOnThis writes: An article on CNN reports results from a team of Japanese researchers who discovered that painting cows to look like zebras makes them less attractive to biting flies. I think they're a shoo-in for a 2020 Ig Nobel Prize. From the article:

A team of Japanese researchers recruited six cows and gave them each black-and-white stripes, black stripes and no stripes. They took photos of the cow's painted right side, counting the number of bites as they happened and watching how the cows reacted. [...]

Zebras' stripes have more than aesthetic value; they help fend off bloodsuckers. Past studies have proven flies are less likely to land on black-and-white surfaces — the polarization of light impairs their perception, so they can't properly decelerate, researchers wrote.
