Ever wondered why zebras have black-and-white stripes? Well, a group of scientists think they developed them to keep away blood-sucking flies.

Researchers put out different coloured models of horses in a field - one brown, one black, one white, and one with black-and-white stripes.

The model with black-and-white stripes attracted the least number of flies.

The team thinks the stripey pattern is a turn-off for flies, because of how it reflects light.

There have been loads of ideas about why zebras have stripes.

Some scientists think it's to confuse predators when they're in a group. Another theory is that zebras use the stripes to recognise each other.
