A weevil is any beetle from the Curculionoidea superfamily. They are usually small, less than 6 mm (&frac14; inch), and herbivorous. Due to the shape of their heads, weevils are commonly known as snout beetles. There are over 60,000 species in several families, mostly in the family Curculionidae (the true weevils). Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil (Stegobium paniceum), which belongs to the family Anobiidae.
