Even bugs are baffled by a zebra’s stripes

The black-and-white-striped body of a zebra creates an optical illusion. In a herd it is difficult to see exactly where one zebra stops and another begins. This can be a challenge for the predators like lions. Zebras are plagued by biting insects, but bizarrely they are unlikely to be bitten by the blood-sucking bugs – Tsetse flies. The stripes baffle the bugs.
