I have two oak trees and something is eating the leaves almost as fast as the tree can produce them. I don't see webs and what leaves I can reach, I don't see anything. Ideas? Something to try? The trees are 20 years old so they are established and fairly large.

It may be a case of oak tatters. While it looks like something ate portions of the oak leaf, insects are not involved. Oak tatters interferes with normal oak leaf development. See the websites below for additional information on oak tatters.
