October Glory Japanese Maple Leaf Damage

Asked October 6, 2016, 11:23 AM EDT

Some leaves on my tree are being eaten away between leaf veins leaving a lacey skeleton-like look. I can't see any pest on the leaves even with a magnifying glass. Any ideas on what could be causing this and what would be the remedy?

Your tree probably had some late season caterpillar feeding. Some caterpillars have gotten large by the end of the summer and so they consume more. Many pupate and turn into the spectacular moths or butterflies. Big caterpillars make big moths and butterflies.

This feeding does not harm established trees. This late in the growing season, trees have had plenty of time to create and store energy. You do not need to take any action--except may keep an eye out for some good-looking critters.
