“Can you tell me if Green Tomato worms can be found around Oklahoma?” asks this reader in her submission. She does not attach any photos, though she notes that she lives in Washington County. “I would like to know if they do, so when I start my garden I can be prepared for them.” First off, we assume that by ‘green tomato worm’, our reader is referring to the tomato hornworm. If that is the case, it might be ample to provide some context. The tomato hornworm is a moth caterpillar which is indeed green in color, and which does feed on tomatoes, among other plants.
