The Curculionidae are a family of weevils, commonly called snout beetles or true weevils. They are one of the largest animal families with 6,800 genera and 83,000 species described worldwide. They are the sister group to the family Brentidae.
Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small – less than 6 mm in length – and herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae. It also includes bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the leaf beetle subfamily Bruchinae, known as "bean weevils", or the biscuit weevil, which belongs to the family Ptinidae.
Anthonomus is a genus of weevils. This genus includes major agricultural pests such as the boll weevil, strawberry blossom weevil, and pepper weevil, as well as promising biological pest control agents such as Anthonomus santacruzi.
The black vine weevil is an insect native to Europe but common in North America as well. It is a pest of many garden plants.
Larinus is a genus of true weevils, comprising about 180 species, mostly in the Palaearctic region with some species introduced to North America. Turkey appears to have a significant diversity of the group, with more than 50 species recorded in the eastern part of the country.
Sitona is a large genus of weevils in the family Curculionidae native to the Nearctic and Palaearctic regions. Over 100 species have been described. Sitona is easily distinguished from related genera by flat, recumbent scales on the mandibles, by the absence of an oval scar on the mandibles, by short and broad rostrum with a deep, longitudinal, median groove, and by dense scales on the body.
The Entiminae are a large subfamily in the weevil family Curculionidae, containing most of the short-nosed weevils, including such genera as Entimus, Otiorhynchus, Phyllobius, Sitona, and Pachyrrhynchus. In comparison with their stunning diversity, only a few of these weevils are notorious pests of major economic importance. Entimines are commonly encountered in the field, including urban environments, and abundant in entomological collections.
Otiorhynchus ovatus, the strawberry root weevil, is one of the many species in the weevil family (Curculionidae), occurring across Canada and the northern United States. The species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. Its name comes from its affinity for strawberry plants, which form a large part of its diet. They are, however, known to feed on other plants as well. Occasionally the larvae cause serious damage to seedlings and young transplants in plantations and nurseries. It is known to be one of the major pests threatening sub-tropical strawberry farming.
Otiorhynchus armadillo is a species of broad-nosed weevil belonging to the family Curculionidae, subfamily Entiminae.
Otiorhynchus vehemens is a species of broad-nosed weevils belonging to the family Curculionidae, subfamily Entiminae.
Entimus is a genus of broad-nosed weevils belonging to the family true weevil and the Entiminae subfamily.
Anchylorhynchus is a genus of weevils belonging the family Curculionidae and subfamily Curculioninae. It currently includes 25 described species distributed from Panama to Argentina. Members of the genus are pollinators of palms in the genera Syagrus, Oenocarpus and Butia, with adults living in inflorescences and larvae feeding on developing fruits. The first instar larvae of Anchylorhynchus have an unusual morphology, being specialized on killing other larvae infesting the palm fruits.
Otiorhynchus meridionalis, the lilac root weevil, is a species of broad-nosed weevil in the family Curculionidae. It is found in North America. Lilac root weevils are shiny, brownish-black beetles, about 0.25 inches (0.6 cm) with long snout (rostrum) and geniculate (elbowed) antennae. They are common landscape pests, feeding on lilac, euonymous and peonies.
Naupactus leucoloma is a species of broad-nosed weevil in the beetle family Curculionidae.
Otiorhynchus crataegi, the privet weevil, is a species of broad-nosed weevil in the beetle family Curculionidae.
Romualdius scaber, known generally as the crusted root weevil or crusted grass weevil, is a species of broad-nosed weevil in the beetle family Curculionidae. It is found in Europe and North America.
Isodacrys is a genus of broad-nosed weevils in the beetle family Curculionidae. There are 20 described species in Isodacrys, ranging from the southern United States of America to Honduras.
Sphenophorus brunnipennis is a beetle in the Dryophthoridae family.
Polyteles is a South American genus of broad-nosed weevils in the subfamily Entiminae, tribe Entimini. There are seven described species distributed in Argentina, Bolivia, Brazil, Ecuador, Paraguay, Peru, and Uruguay.
