The larvae feed on foliage, stripping trees in bad years. Larvae can be controlled with Bacillus thuringiensis. Traditional pesticides may also be used but usually need to be applied by an arborist. It infects the roots of many plants, yellowing the leaves, causing wilting and dieback. Signs of infection include pale brown mushrooms growing around the base of the plant and fan-shaped, whitish mold under the bark.
Infected plants are hard to save.
