The beetle first digs an oblique hole in the fruit with her snout, enlarging it at the bottom. She then lays an egg in the mouth of the hole, pushing it to the bottom with her snout.

The beetle first digs an oblique hole in the fruit with her snout, enlarging it at the bottom. She then lays an egg in the mouth of the hole, pushing it to the bottom with her snout. Finally she cuts a crescent- shaped flap around the egg. Her purpose in doing this seems to be to make a dead spot, so that the growing of the fruit at this point will not crush the egg. This crescent is the mark by which to distinguish the curculio's work, and it is ren- dered even more conspicuous by a copious exudation of clear gummy substance from the growing fruit. The larva feeds in the pulp, generally about the stone, and the fruit, except in case of the cherry, falls prema- turely. When the larval growth is attained, in three to five weeks, it burrows out of the fallen fruit and into the ground to a depth of four to six inches. Here it pupates and emerges the same season as the little, rough, brownish beetle shown in Fig. 84. It may be recognized by the elongated hump of what appears to be black sealing wax on each wing cover. The winter is passed in cracks about buildings and in the bark of trees, whence the beetles come forth with the peach and plum blossoms, ready to begin their work of destruction.
