Japanese beetles do damage to most trees by eating the leaves. They focus their feeding on the parts of the leaves between the leaf veins. After feeding, the leaves have an appearance like lace. They typically start at the top of the tree and work their way down. After a season of feeding, the affected trees will look (from a distance away) like they would in late autumn.

The fruit on fruit trees is typically subjected to a meandering surface feeding by the beetles.

Damage done to the turf by the grubs will have a brown, dried out or burnt appearance.
