Rice weevil

Description:

Adults are about 1/8 inch long, reddish brown to black with four reddish or yellowish spots on the wing covers (elytra). The head bears a slender snout and the shield behind the head (pronotum) has course round punctures. The elytra have deep lines (striae) and course punctures. Larvae are legless, white and rotund with a distinct head capsule.

Habitat:

Mouthparts are for chewing. Found in stored grains of all types including wheat, corn, oats, barley, sorghum, macaroni, and other grain products. They may also infest grain in the field. Larvae hollow out kernels of grain and usually attack whole kernels. Holes in the side of the grain are made by adults and by the emerging adults. They build up in numbers in stored grain.
