 European Gypsy Moths

April 2004

 

Why are gypsy moths a problem? Infestations cause damage by defoliating trees. Outbreaks of gypsy moths have defoliated large forests. Defoliation stresses trees, reduces food and habitat for other animals, and can reduce shade over creeks that is vital to fish and other aquatic organisms.
