Cutworms often feed at the base of plants, however, the variegated cutworm which feeds on hosta leaves will climb up into the "canopy". They create holes of varying sizes in the leaf blade from their feeding which occurs at night. There may be several generations each growing season.

Although not usually a large problem in most hosta gardens, cutworms may be managed in several ways. During the day, the 1/2 to 3/4 inch long creatures hide in the soil at the base of the plant. Scraping the soil with your fingers may help you discover them. Or, at night, with a flashlight, you may be able to find them feeding and dispatch them in a cup of soapy water. In the very rare case where damage is severe, check with your Cooperative Extension Service for pesticide recommendations in your state.
