Weevil (Lixus angustatus)

A weevil is any beetle from the Curculionoidea superfamily. They are usually small, less than 6 millimetres (0.24 in), and herbivorous. 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. Many weevils are damaging to crops. The grain or wheat weevil (Sitophilus granarius) damages stored grain. The boll weevil (Anthonomus grandis) attacks cotton crops. It lays its eggs inside cotton bolls, and the young weevils eat their way out.

Habitat

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.
