I have long since become accustomed to the idea that insect-eaten leaves are a sign of a healthy garden, but I'm curious: what's eating the leaves? Whenever I inspect the leaves with holes in them or corners chewed off (above and below), I see no hungry insects or other critters - to my disappointment. If I set up an all-you-can-eat buffet in my backyard, the least the diners could do is show themselves to me!
