The insect, which is popularly known as the “Grape-root 
Borer,” ranges from Vermont to the Carolinas, and westward as 
far as Missouri. It inflicts considerable damage upon both wild 
and cultivated grape-vines. The moth resembles the wasps of 
the genus Polistes, whence the name.

moth,” because of its resemblance to a hornet, is found abun¬ 
dantly in Europe, but less commonly in North America. Its

The insect, which is popularly known as the “Blackberry- 
borer,” is not at all uncommon. The grub-like larvae infest the
