is butternut woolyworm harmful?

Asked September 18, 2017, 9:41 AM EDT

Hi. Today, Sept 18, suddenly I see larvae on our walnut tree that I identify as butternut woolyworm. Are they harmful? What should I do? Why are they appearing so late in year? Thanks.

With this late emergence, should not be a problem for your tree. See:
for more information.
