BROAD-NOSED GRAIN WEEVIL.* 
The broad-nosed grain weevil is a small dark-brown snout-beetle 
slightly less than one-eighth of an inch long. In form and color 
it resembles the granary weevil somewhat but differs from it and 
other grain-infesting weevils by having a short, broad snout (see 
figure 8.) 
This weevil is occasionally found in Georgia, and South Carolina 
and is wide-spread in Florida, where it is a serious pest of stored 
grains. It is unable to breed in dry, hard, uninjured grain, but 
attacks soft or damaged grain, or grain that has been attacked by 
other grain insects. It is a strong flier, and, like the rice weevil, 
flies to the cornfields and infests the grain before it becomes fully 
hardened. 
The adult weevils normally live for about five months, and during 
this time the females lay between 200 and 300 eggs. The small white 
eggs are usually laid in broken portions of the grain. They hatch 
in a few days, and the small, white, legless grubs feed on the softer 
portions of the grain until they become fully grown. They then 
change to a white pupal form which in a few days transforms to the
