A weevil is a type of herbivorous beetle. Many weevils are damaging to crops. The grain or wheat weevil damages stored grain. The boll weevil attacks cotton crops by laying its eggs inside cotton bolls, and the young weevils eat their way out. Weevils are often found in dry foods including nuts and seeds, cereal and grain products, such as pancake mix. In the domestic setting, they are most likely to be observed when a bag of flour is opened. Their presence is often indicated by the granules of the infested item sticking together in strings, as if caught in a cobweb.
• Weevils are usually small, less than 1/4 in. and occur in a wide range of colors and body shapes, though many are slender or oval-shaped insects.
• Weevils are usually dark-colored – brownish to black – with some having scales or shiny hairs covering part of their bodies.
• The most distinctive feature of weevils is the shape of their head, which is elongated and forms a snout (sometimes as long as its body) with a mouth at the end.
