I was going to get the morning papers the other day when I noticed that the apple tree in the corner of the yard looked strange; it was fuzzy on one side but had full leaves on the other. When I got closer, I saw that on the "fuzzy" side, the leaves had been eaten away except for the main vein that runs up from the branch through the center of the leave. It hadn't been like that the morning before so either a flock of locusts came through during the day or night and ate the leaves. No sight of any bugs around or on the tree.

The "fuzzy" area was 6-10 feet above the ground. None of the other trees had been damaged and there was no damage on the normal, fully-leaved side of the tree. Any ideas as to what might have caused this?
