This chapter describes cutworms and armyworms. The popular names cutworm and armyworm describe larval habits of certain caterpillars. In many vegetable and field crops, cutworms sever young plants at or near ground level and proceed to the next plant to repeat the process. This feeding pattern contributes greatly to the highly destructive nature of these insects. In turfgrasses, cutworms may sever grass stems, but they usually feed on grass stems and leaves, which causes thinning of turf or “pockmarks,” which appear as sunken areas where the grass blades and stems have been eaten down to the thatch. The chapter then looks at the black cutworm, the variegated cutworm, the winter cutworm, the bronzed cutworm, the fall armyworm, the yellow-striped armyworm, and the lawn armyworm.
