SNOUT BEETLES ATTACKING BUD OR FRUIT 209 
In the early spring the adult beetles appear in the cotton fields 
from their winter hiding places. Usually there are but few of them at 
this time. When the squares 
begin to form, eggs are laid 
within them, and as the grub 
develops the square usually 
falls to the ground. A pupal 
stage is passed within the 
square, and soon a second 
generation of adults is out. 
Eggs are now laid in the 
squares as before. There are ‘ oe

the course of the season. 
When the squares are no longer available, eggs are laid in the 
bolls in similar fashion. 
Hibernation of the adult weevils does not begin until late in the 
season, long after the regular crop of cotton is picked. When the 
first frosts come, the adults seek shelter in which to spend the winter, 
while the immature stages die. At this time the adults fly to 
considerable distances, seeking places to hibernate.
