Q&A - What are these green caterpillars by my peanut plants?

Question:
Hey Chris! I was pulling weeds around my peanut plants today and ran across several of these green caterpillars in the soil. What are they, and what should I do about them?

Answer:
This is an alfalfa caterpillar. They feed on legumes. They can cause major damage to alfalfa. If you would like to control it, a BT product will do the trick.
