Western bean cutworm adults have not yet started to fly in Iowa, but there may be some confusion over misidentification of other moths that are now flying. Several species are now being collected in Ames, and if you are unfamiliar with the western bean cutworm, then these moths may present challenges for proper identification. The most commonly collected moths during the second week of June were armyworm, yellowstriped armyworm, and spotted cutworm. A brief description of these three species and the western bean cutworm follow:
