You may have noticed webs being formed around the tips of the branches of pecan and sweet gum trees. You may have also noticed defoliation under the webbing on these trees.

This most likely indicates infestation of the fall webworm. In the south, the fall webworm uses deciduous hardwood trees and some evergreen trees as a host.

The fall webworm, favors hickory, pecan, persimmon, and sweet gum.
