I have had more inquiries this spring than in the past several years regarding brown and gray moths flying around lights at night or being flushed from weedy areas in fields. There are dozens of species of moths that occur in Iowa in the spring, but only a few are potential pests. The eight most common moths collected during mid-May in a light trap in Ames were armyworm, black cutworm, celery looper, spotted cutworm, and variegated cutworm. All of these moths have multiple generations in the Midwest, so it is possible to see them again in mid- or late summer.
