So, What's in the News today?
- A study by Gábor Horváth and colleagues from Hungary and Sweden have found that the zebra has evolved its stripes to fend off blood sucking insects
- Horseflies are attracted to horizontally polarized light which looks (to them) like long stretches of water, where the bugs can lay eggs
- Female horseflies are also attracted to linearly polarized light reflected from hides
- Horse flies are more attracted to darker hides than white ones
- Zebras have dark skin and then develop white stripes when in the womb
- The team tested stripe width in relation to horsefly attraction
- They concluded that zebras have evolved their stripes so that the stripes on the coat are narrow enough to ensure minimum attractiveness to horseflies
