The Curculionidae are the family of the "true" weevils. They are one of the largest animal families, with 6,800 genera and 83,000 species described worldwide.
Weevils are a type of beetle belonging to the superfamily Curculionoidea. They are usually small, less than 6 mm (0.24 in), and herbivorous. About 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil, which belongs to the family Ptinidae.
The New York weevil is a species of primitive weevil; large for weevils (12–18 mm), it is covered with fine bristles and has a regular pattern of light and dark spots. It occurs in the eastern United States and southern Canada.
The bean weevils or seed beetles are a subfamily (Bruchinae) of beetles, now placed in the family Chrysomelidae, though they have historically been treated as a separate family. They are granivores, and typically infest various kinds of seeds or beans, living most of their lives inside a single seed. The family includes about 4,350 species and are found worldwide.
Caridae is a small Gondwanan family of weevils. They are considered part of the primitive weevil group, because they have straight rather than elbowed antennae. The insertion of the antennae on the rostrum cannot be seen from above. Caridae also lack spiracles on abdominal tergites 6 and 7. The prothorax lacks lateral carinae. It has been suggested that the fossil weevil Eccoptarthrus belongs in this family, which would result in a change in the family name ; this proposal has been rejected by most coleopterists (e.g.)
The New Zealand giraffe weevil, Lasiorhynchus barbicornis, is a distinctive straight-snouted weevil in the subfamily Brentinae, endemic to New Zealand. L. barbicornis is New Zealand's longest beetle, and shows extreme sexual dimorphism: males measure up to 90 mm, and females 50 mm, although there is an extreme range of body sizes in both sexes. In males the elongated snout can be nearly as long as the body. Male giraffe weevils use this long rostrum to battle over females, although small males can avoid conflict and 'sneak' in to mate with females, sometimes under the noses of large males. The larval weevils tunnel into wood for at least two years before emerging, and live for only a few weeks as adults.
The tooth-nosed snout weevils, Rhynchitidae, are small beetles that are usually found vegetation. They usually use buds, fruits, or seeds for oviposition. The tooth-nosed snout weevils receive this name due to the teeth on the edges of their mandibles.
