Locust leafminer, Odontota dorsalis (Thunberg), is a leaf-feeding beetle native to North America. Black locust (Robinia pseudoacacia) is the preferred host for the larval stage, but adult locust leafminer also feeds on honey locust (Gleditsia triacanthos), apple, oak, birch, beech, elm, cherry, and hawthorn. Locust leafminer is known to feed on soybean leaves as both larvae and adults, but damage to this crop is considered minor.
