description Maize Weevil Overview
The maize weevil, Sitophilus zeamais, is a snout beetle that attacks stored maize and other cereal grains. Adults are usually dark brown to black with four reddish or yellowish spots on the wing covers, and they have functional wings, allowing them to fly between grain stores. The female places an egg inside a kernel, seals the opening, and the larva develops within the grain, which makes infestations difficult to detect from the outside.
