This grub devours dur-ing the summer, the contents of the acorn, and in the autumn drops, withthe rifled fruit, to the ground, where it soon gnaws its way out through acircular hole and buries itself for the winter. It becomes a pupa in thespring, and eventually issues as a beetle. After the original depredator has vacated its tenement, a little guest-moth comes along and drops an egg into the already ruined acorn. Theworm hatching from this egg grows fat upon the crumbs left by the formeroccupant
