Weevils are beetles belonging to the superfamily Curculionoidea. They are usually small insects and are herbivorous. There are almost 100,000 known species around the world. Some other beetles are not technically weevils but are still commonly known as “weevils”, such as the biscuit weevil which belongs to a different family.
Many weevils are considered a pest because of the damage they can cause to gardens and crops. The grain or wheat weevil damages stored grains. The boll weevil attacks cotton crops. It lays its eggs inside cotton bolls, and the larvae eat their way out.
