"Once horse flies get close to zebras, they tend to fly past or bump into them," said Professor Tim Caro, a scientists at the University of California. And on moonless nights, the stripes are particularly difficult for all species to distinguish beyond 9 meters (about 29 feet.)

De zebra’s blijken de strepen van iets grotere afstand dan roofdieren waar te kunnen nemen, maar toch is het niet aannemelijk dat de strepen een sociale functie hebben, zo stellen de onderzoekers. But now researchers have found a black-and-white checkered pattern will, too — making them … When the team put zebra-pattern coats on the horses, fewer flies landed on them.

"Stripes may dazzle flies in some way once they are close enough to see them," said study author Dr Martin How, a scientist at the University of Bristol. The study, published in the journal PLOS ONE, found stripes are not used for camouflage, or a means of breaking up the outline of the zebra to make it less conspicuous, as at the point at which predators can see zebra stripes they will already have heard or smelled the zebra prey.

Op basis daarvan schatten ze vanaf welke afstand leeuwen en hyena’s overdag, in de schemering en ‘s nachts in staat waren om de strepen van de zebra te zien. Scientists have long suspected that the stripes help zebras hide … We simulated a biologically motivated motion detection algorithm to analyse motion signals generated by different areas on a zebra's body during displacements of their retinal images.
