Evolution is two-sided race. Insects breed/evolve much faster than large mammals. One must wonder why they haven't evolved the brainpower to overcome this trickery. The difficulty of feeding on zebra must not be enough of an evolutionary pressure ... until all the other animals start evolving stripes too.

That is a good question. Given the short lifespan of the creatures, one hypothesis is their evolution is stuck in a high-walled local maxima.
