Orange (red headed) race of fall webworms (left) or the blackheaded race of fall webworms (right) could be found in the webbing.  Photo provided by:  Lacy L. Hyche, Auburn University, Bugwood.org

One management option is to tear open the webbing so natural enemies such as the assassin bug pictured above can eat the caterpillars.  Photo provided by:  Lacy L. Hyche, Auburn University, Bugwood.org
