According to the species, they can vary in size from 3 millimeters to 10 millimeters in length. Weevils can have dark colors that range from dark brown, black, or sometimes reddish. The most notable physical trait of weevils is their head form. Weevils that are adults may have a head that appears like a snout in the place where their mouths are. For instance, the Curculionidae family is known for its extended snout, which can be the same length as their bodies. But in the Bruchidae family, the cowpea weevils are different from other species.
