Corn Earworm The corn earworm is also known as the tomato fruitworm or the cotton bollworm. It is the caterpillar of a night-flying moth that has a wingspread of about 1V2 inches. The moths vary in color from light olive green to grayish brown or yel- lowish brown. Female moths lay their eggs on the leaves of cole crops or on grasses nearby. The eggs are ribbed, shaped like a flattened ball, and light yellow to dusky brown. Newly hatched corn earworms are whitish and have black heads. The older ones are green, greenish brown, or green- ish black; they are usually marked with stripes of yellow, brown, green, and black; they have yellow heads. Full-grown earworms are about IV2 inches long. Mature caterpillars burrow 2 to 6 inches into the soil and transform into shiny, light brown pupae about three- fourths inch long. A single corn earworm may seriously damage or destroy the bud of a cole crop plant,.
