The soybean leafminer, Odontota horni, is a minor pest of soybean. This beetle seems to be fairly common in soybean this spring because reports of this insect have come in from eastern, central, and southwestern Iowa. The adult soybean leafminer is approximately 6 mm in length and bright red with a narrow black stripe extending down the back between the wing covers. The antennae, head, and legs also are black.
