If the leaves on your linden, birch, or crabapple suddenly look like brown lace this month, you are seeing Japanese beetles at work. Mid-July is their peak across Metro East Illinois, and they feed in groups.
The beetles eat the soft tissue between the veins and leave the veins behind, which gives leaves that see-through, skeletonized look. A heavy infestation can brown out the top of a canopy in a week, and the beetles tend to pile onto the same favored trees year after year.
Here is the reassuring part. A healthy, established tree can usually shrug off a season of Japanese beetle feeding, even when it looks alarming from the ground. The trees that get into trouble are the ones already stressed by drought, poor pruning, or a weak structure, where beetle damage becomes one problem too many.
That is where a walk-through helps. Sometimes the right call is patience and good watering, and sometimes the tree was already declining and the beetles just made it obvious. Knowing the difference is what keeps a minor summer nuisance from turning into a removal down the road.
Are you seeing skeletonized leaves on any particular tree in your yard this month?
