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 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.
Chrysolopus spectabilis is a species of weevil found in south-eastern Australia. It was discovered during James Cook's first voyage, and became one of the first insects to be described from Australia. The weevil measures up to 25 mm (1.0 in) long and includes distinctive metallic green and black scales. It is found only on 28 species of the plant genus Acacia.
The palm weevil Rhynchophorus ferrugineus is one of two species of snout beetle known as the red palm weevil, Asian palm weevil or sago palm weevil. The adult beetles are relatively large, ranging between 2 and 4 centimetres long, and are usually a rusty red colour—but many colour variants exist and have often been classified as different species. Weevil larvae can excavate holes in the trunks of palm trees up to 1 metre (3.3 ft) long, thereby weakening and eventually killing the host plant. As a result, the weevil is considered a major pest in palm plantations, including the coconut palm, date palm and oil palm.
Hadramphus tuberculatus is a rare weevil endemic to Canterbury in the South Island of New Zealand. It was thought to be extinct in 1922 but was rediscovered in 2004.
Anthonomus eugenii is known as the pepper weevil. This beetle feeds and lays eggs on plants in the genus Capsicum and a few species in the genus Solanum. A. eugenii is native to Mexico, however, it is an important pest of Capsicum in Florida, Puerto Rico, and Central America.
Pissodes strobi, known as the white pine weevil or Engelmann spruce weevil, is the primary weevil attacking and destroying white pines. It was described in 1817 by William Dandridge Peck, professor of natural history and botany at Harvard University. The weevil is dark brown with white spots and is native to North America.
Hadramphus, commonly known as knobbled weevils, is a genus of flightless molytine weevils from the family Curculionidae. It is endemic to New Zealand and consists of four species.
Myllocerus undecimpustulatus, known generally as the Sri Lanka weevil or yellow-headed ravenous weevil, is a species of oriental broad-nosed weevil in the beetle family Curculionidae. It damages crops and is resistant to controls. It has spread.
Myllocerus is a genus of oriental broad-nosed weevils in the beetle family Curculionidae. There are at least 330 described species in Myllocerus.
Eudiagogus is a genus in the beetle family Curculionidae. They are commonly known as sesbania clown weevils, in reference to the fact that they eat plants of the genus Sesbania. There are about five described species in Eudiagogus.
Curculio sayi, the small or lesser chestnut weevil, is a species of true weevil in the family of beetles known as Curculionidae.
Pactorrhinus is a genus of broad-nosed weevils in the beetle family Curculionidae. There is at least one described species in Pactorrhinus, P. grisescens.
Cionomimus is a genus of true weevils in the beetle family Curculionidae. There are about 10 described species in Cionomimus. Adults are associated with Phoradendron plants, feeding on their reproductive organs.
Pissodes striatulus, the balsam bark weevil, is a species of true weevil in the beetle family Curculionidae. It is found in North America.
Tanymecus is a genus of broad-nosed weevils in the beetle family Curculionidae. There are at least 100 described species in Tanymecus.
Hormorus is a genus of broad-nosed weevils in the beetle family Curculionidae. There are at least two described species in Hormorus.
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.
Lyperobius huttoni is a New Zealand weevil found in alpine areas of the South Island and at sea level around the Wellington coast. It feeds only on speargrass (Aciphylla). Weevils from the endangered Wellington population have been translocated to predator-free Mana Island.
