Mamestra configurata, the Bertha armyworm, is a moth of the Noctuidae family. It is found in the western part of the North America (including Alberta, British Columbia, Washington, New Mexico, California[2]) and Mexico.

Adults are grey black with a silvery-whitish kidney shaped spot and fringe on each forewing.

The larvae feed on canola. First feeding on the leaves, but later also feeding on the pods. Full-grown larvae drop to the ground in mid to late August to pupate.[3]
