They immediately fly into the top of the tree, and there feed upon the epidermis of the tender twigs, and the petioles of the leaves, often wholly denuding the latter, and causing the leaves to fall. They deposit their eggs, two or three in a place, upon the trunk and branches, especially about the forks, making slight incisions or punctures, for their reception, with their strong jaws. As many as ninety eggs have been taken...
