About two years ago, scientists tested the “biting flies” theory using horse models covered in a sticky substance.Horseflies tended not to land on the fake horses that had stripes painted on them. The researchers felt that the stripes confused the flies'“navigational system (導(dǎo)航系統(tǒng))” — the flie

Then they looked up information about where biting flies and zebra-enemies (like hyenas 鬣狗) lived.They have discovered that zebras tend to live in the same areas where biting flies are present, which has supported their theory. Now that the researchers are pretty certain the stripes help zebras discourage flies, they want to do more research with that theory in mind.They wi
