Sitophilus zeamais 
Length: Approximately 5 mm 
A small snout beetle. It varies from dull red-brown to nearly black and is usually marked on the back with four light reddish or yellowish spots. It is slightly larger than the rice weevil and has more distinct colored spots on the forewings. 
The maize weevil has fully developed wings beneath its wing covers and can fly readily. It is a stronger flier than the rice weevil allowing it to distribute itself more easily. The thorax is densely pitted with somewhat irregularly shaped punctures, except for a smooth narrow strip extending down the middle of the dorsal (top) side.
