We have started to see cutworm damage in Ohio corn. Black cutworm (BCW) is the prime offender, though other species exist. Adult BCW (moths) are migrants from the south that start moving into Ohio in April, and lay eggs that hatch into the cutworm caterpillars. Although there are some hotspots for egg laying, these predictions are far from exact. Moths tend to seek out fields with a lot of weeds, especially winter annuals such as chickweed, to lay their eggs.
