moth and, if neglected, they may destroy the entire crop 

 of a vine while the blossom buds are opening. The vines 

 should be daily examined at this season and, after securing 

 specimens for the school collection, every larva should be 

 destroyed. The insect being single brooded, thorough 

 attention at the proper time will do away with the pest. 



The Grape-Leaf Folder, Desmia maculalis. This is another 

 common enemy of the grape and should be treated, like 

 the plume moth, by hand picking while in the early larval 

 stages ; the conspicuously folded leaves make this easy 

 and effectual. 



The Grape-Berry Moth, Eudemis botrana. This insect 

 often destroys nearly the whole crop of grapes in a garden. 

 The larvae pass 

 the winter in co- 

 coons attached to 

 the leaves, and if 

 these are burned 

 in the fall, the 

 pest may be 

 greatly abated. 



The Sphinxes, or 

 Hawk Moths, might 

 be treated among 

 our most beauti- 

 ful and interest- 

 ing insects were it not for the fact that the larvae of at 

 least ten species feed upon the leaves of the grape, and 

 their enormous size makes it possible for a single larva 

 to strip and kill a young grapevine in two or three days. 

 The sphinxes are the large, narrow-winged moths, often
