Locust leafminer is the leafmining beetle that devastates black locust along the highway, leaving trees with a scorched appearance. Most trees survive the unsightly damage. But locust leafminer can also infest yellowwood, Japanese pagoda tree and golden chain tree. Look for second generation adults feeding now and control with Orthene. New larvae should begin developing in blotch mines in July.
Merit can control feeding larvae.
