COFFEE-BEAN WEEVIL.’ 
The coffee-bean weevil is a very 
active, robust beetle from two- 
sixteenths to three-sixteenths of 
an inch long; dark brown in 
color, clothed with a mottled hight 
and dark-brown pubescence. It 
may be easily recognized from the 
accompanying illustration (fig. 
9): 
This weevil is found in many 
countries and is extremely abund- 
ant in the Southern States, where 
it breeds in dried fruit, coffee ber- 
ries, cornstalks, corn, and the seed 
and seed pods of an almost end- 
less variety of plants. It is a 
strong flier and is frequently to 
be seen in the cornfields of the 
South on the exposed and dam- 
aged ears. It lays its eggs in the 
soft kernels of corn and breeding 
continues after the corn has been 
harvested and placed in storage. 
It does not cause much damage 
to corn in storage, as the corn be- 
comes too hard to be attractive. It 
may, however, be very abundant 
locally in corn in Florida dur- 
ing the first three months of stor- 
age, and has been reported as com- 
seeds in Honolulu. Taking the 
country at large, the coffee-bean 
weevil is a very minor grain pest.
