PILE OE 120,000 WEBS OE THE BROWN-TAIL MOTH GATHERED AND DESTROYED AT 



YORK, MAINE 



York Harbor, Maine, has become thoroughly infested with the brown-tail moth. This 

 illustration is a photograph of a pile containing 120,000 of the winter nests of the brown- 

 tail gathered and destroyed in an effort to free the community from this pest. More than 

 40 million larvse were contained in these nests. The brown-tail moth was imported by a 

 Boston florist about 20 years ago on roses from Holland or France. It is a serious enemy 

 of orchard, forest, and shade trees and ornamental shrubbery, and has long been recognized 

 as one of the worst orchard pests of Europe. During the last three years it has been 

 imported in enormous numbers on nursery stock from northern France, Holland, and 

 Belgium, and carried to 22 States. There is no law to prevent such importations. The 

 hairs on the caterpillars produce the brown-tail rash, which often affects residents of 

 infested districts.
