It occurs all through the southern states, west to Kansas, and as far north as Maryland along the north shore of the Potomac river. The adult insect issues from the old cornstalks in the spring. Soon after the young com comes up it lays its eggs upon the leaves near the axils, and the larva upon hatching penetrates the stalk at or near the joint and commence-? to tunnel, usually upward through the pith. When ready to transform it bores to the surface of the stalk, making a hole for the exit of the future moth, then.
