With uncanny precision, this grasshopper (Chorotypus sp.) displays its mimicry of a dead leaf down to the finest details. Why do some organisms go to such extreme lengths for their camouflage while others can get by with a much simpler appearance? The answer of course is largely due to what they are hiding from: there is a direct correlation between the detail of camouflage and the visual acuity of their specific predators. In this case, the sharp eyes of small insectivorous birds, like the hands of a master craftsman, provide the driving force to some of the most eccentric insect appearances.
