Fall Webworm—Hyphantria cunea
The most notable aspect of this pest is the unsightly silken web that it produces. Many times, there are many of these webs per tree. These webs are started near the tips of the branches and gradually are extended down the branch towards the trunk. Although not considered a serious forest pest, the ugliness of the webs can cause them to be considered a significant pest of nurseries and landscapes.
