This is a picture of the back of an aspen leaf. I noticed that the aspen trees had the color of a Russian olive and I just had not remembered that before. So one evening at a campground I looked closely at the leaves. Most of the trees have this pattern. There is a very small moth that looks like a small piece of cottonwood fuzz that blows through the air. Well, the moth lays it eggs on the leaves and then the larva make this pattern as it eats part of the leaf. I decided that it looks just like the stippling that would be on a quilt. All the leaves are different and have interesting patterns.
