Sitophilus linearis, commonly known as the granary weevil, is a small beetle belonging to the family Curculionidae. It is a common pest of stored grains, particularly wheat, rice, and corn. Adult granary weevils are about 3-4 mm long, with a long snout and reddish-brown coloration. They infest grains by laying eggs inside the kernels, and the larvae develop within the grain, causing damage and reducing its quality.
