The green-striped mapleworm. (Anisota rubicunda (Fab.)), a native of North America, is distributed widely throughout the eastern half of the United States and the southern parts of adjacent Canadian Provinces. Its southern range extends from the Carolina coast to the gulf coast in Alabama and Mississippi. It has been recorded as far west as Nebraska and Kansas. The insect causes heavy defoliation throughout its range but is most destructive near its southwestern limits.
