Oak Leaf Miner Damage: Identification and Cleanup

Blotchy brown patches on oak leaves are caused by solitary oak leafminer larvae (Cameraria hamadryadella). The moth larvae feed between leaf layers, creating mines.

Management

Rake and destroy fallen leaves promptly to remove pupae. If infestation recurs next year, consult an arborist for treatment options.
