weevil (redirected from Weevily)

weevil, common name for certain beetles of the snout beetle family (Curculionidae), small, usually dull-colored, hard-bodied insects. The mouthparts of snout beetles are modified into down-curved snouts, or beaks, adapted for boring into plants; the jaws are at the end of the snout. The bent antennae usually project from the middle of the snout. The largest weevils are about 3 in. (7.6 cm) long, with the average length being about 1-4 in. (0.6 cm). The snout varies greatly in length among the different species; in the curculios, or nut weevils, it may be longer than the body. Different weevil species attack different parts of plants—fruits, seeds, leaves, stems, or roots. In most species the female lays her eggs inside the plant tissue, on which the growing larvae feed. The granary weevil and rice weevil are serious pests of stored cereal grains. The thousands of other destructive weevil species include the sweet-potato, vegetable, alfalfa, clover leaf, strawberry, and pine weevils, as well as the cotton boll weevil, the most serious weevil pest in the United States. The seed weevils, including the bean weevil, are not true weevils, but boring beetles of another family; they feed on leguminous crops, such as peas and beans. Weevils cause millions of dollars' worth of damage annually. The bark beetles, or engraver beetles, are related to the weevils. True weevils are classified in the phylum Arthropoda, class Insecta, order Coleoptera, family Curculionidae.

weevil

 or snout beetle

Any of about 40,000 beetle species in the largest family of beetles, Curculionidae, which is also the largest family in the animal kingdom. Most weevils have long, elbowed antennae that may fold into special grooves on the prominent snout. Many species are wingless. Most species are less than 0.25 in. (6 mm) long, are plainly coloured and marked, and feed exclusively on plants. Some species are more than 3 in. (80 mm) long. The larvae may feed on only a certain part of a plant or a single plant species; adults are less specialized. The family includes many destructive pests, including the boll weevil.
