SEASONAL HISTORY. 
EMERGENCE OF MOTHS. 
There is one generation annually. The insect pupates in the fall, 
hibernates in the pupa stage, and the moths emerge in early summer. 
During the season of 1916 the earliest emergence from a lot of 36 
cocoons was June 9 and the latest June 24, the majority emerging 
from June 12 to 15, inclusive. No adults were reared in either of the 
two previous seasons, but in 1914 larvee were found in the field as 
early as June 18, indicating that moths must have emerged as early 
as June 1. In 1915 the larve appeared in the field about the same 
time as in 1916. The data relating to emergence of moths in 1916 
are given in Table II.
