Corn Earworm—Helicoverpa zea
Corn earworm does the most damage to corn and tomatoes but they also feed on several other vegetables, many field crops, some ornamentals, and a wide variety of wild plants. Early caterpillars damage corn by feeding in the terminals of young plants; later caterpillars feed on the kernels of older plants. Tomatoes, and occasionally peppers, are damaged mostly by the larvae boring into the fruit.
