TIME OF EMERGENCE OF MOTHS OF THE FIRST BROOD. The earliest moth of the first brood emerged July 28 (Table II). It will be noted from the curve of figure 2 that the maximum of emergence occurred unusually early—August 3. Throughout the month of August there was a constant and large emergence. The. FIG. 2.—Emergence curve of first-brood moths in 1909, at Douglas, Mich. (Original.) great irregularity of the curve in figure 2 is largely due to the fact that the banded trees from which the rearing material was obtained were only examined once a week. However, certain of the irregu- larities of the curve are due to climatic influences. Table II.—Emergence of moths of the first brood or summer brood at Douglas, Mich., 19G9. [Records by W.
