If stripes are for insects not biting, then how come some species have developed only partial stripes? Would not make sense to get all the flies to concentrate on your non striped body-parts... Against lions this makes perfect sense as having striped backside makes the overall shape harder to grasp.
Its not that I agree with the parent but did you read the linked article?
"The results may help explain why zebras' skinniest stripes are on their faces and legs. "That's also the place where you have the thinnest skin," said Åkesson, of Sweden's Lunds University."
But as I stated up thread even if this research was definitive it does not preclude the camouflage benefits...
