Sitophilus oryzae 
Length: Approximately 3 mm 
Small snout beetle; varies from reddish brown to nearly black and is usually marked on the back with four light-reddish or yellowish spots. Resembles the granary weevil in form but differs in color and markings. It has fully developed wings beneath the wing covers. The thorax is densely pitted with somewhat irregularly shaped punctures, except for a smooth narrow strip extending down the middle of the upper (dorsal) side. 
The larvae can also develop in farinaceous products, 
buckwheat, peas, acorns, chestnuts, and cottonseed; the weevil also feeds on flour, hemp-seed, biscuits, waffles, white bread, and tobacco
