The larvae or caterpillars of some moths are called cutworms because of the manner in which they cut down young plants as they feed. The adults are night-flying moths and do not cause damage.

You can stop the cutworm damage with a physical barrier: Place foil or paper wraps or cardboard collars around transplants; extend a few inches into the soil and several inches up the stem. Or, you can use a permethrin or neem oil based insecticide to kill the cutworms. Be sure to apply according to label directions.
