The Grape-Leaf Folder, Desmia niaciilalis. — 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, Etcdemis 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 larvse 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.
