Earworms are also referred sometimes as the fruit worm. They look like caterpillars and can grow over an inch in length. Their color range can be green, brown, yellow or tan and have black or brown stripes on their sides.
They lay their eggs in the spring then continue to eat the silk of corn before it gets to the actual ear. However, this pesky insect does not just limit itself to corn. It also goes after beans, peas, peppers, potatoes, squash and tomatoes.
