description Rice Weevil Overview
The rice weevil, Sitophilus oryzae, is a small snout beetle that infests stored cereal grains in many parts of the world. Adult beetles are usually reddish-brown to nearly black and have four lighter markings on the wing covers; unlike the granary weevil, they have functional wings and can fly. Females lay eggs in individual kernels, where the larvae develop, so infestations can damage whole grains before the insects are noticed.
