Abstract

Black cutworm moths (Photo 1) do not overwinter in Iowa and must migrate north annually. Black cutworm moths have been collected in Iowa since the beginning of April 2015. Seeing significant moth captures in early and mid-April is unusual and could indicate a more frequent incidence of vegetative crop injury compared to other years. There have been reports of black cutworm moth trap catches from other states besides Iowa, including Minnesota, Illinois, Indiana, Missouri, and Kentucky. In some places, such as Indiana, peak flights are being reported. A peak flight is a specific number of moths caught in a trap that signals when to begin adding up temperature data to figure out when to scout for larvae.
