bean weevil

insect species
Also known as: Acanthoscelides obtectus

Quick Summary

The bean weevil, specifically Acanthoscelides obtectus, is a small weevil native to America that has become a global pest. These insects, belonging to the subfamily Bruchinae (seed beetles), are oval or egg-shaped and typically black or brown.12

The life cycle of the bean weevil involves the female depositing eggs on dry beans. The larvae then burrow into and feed on the seeds. This behavior makes them a significant threat to both growing and stored beans. While similar to the pea weevil, the bean weevil differs in its egg-laying habits and the absence of white markings on its wing covers. Bean weevils are among the many insect species that can damage crops and stored products.1234
