This appears to be Japanese beetle damage. Fruit trees (ornamental or producing) are very attractive to these insects. When they feed they skeletonize the leaves that look lacy and then brown. The beetles emerge in late June then usually die off in the first week in August,  so controlling them now would be ineffective.
