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. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil, which belongs to the family Ptinidae.
Solanum carolinense, the Carolina horsenettle, is not a true nettle, but a member of the Solanaceae, or nightshade family. It is a perennial herbaceous plant, native to the southeastern United States that has spread widely throughout much of temperate North America. It has also been found in parts of Europe, Asia, and Australia. The stem and undersides of larger leaf veins are covered with prickles.
Diaprepes abbreviatus is a species of weevil that is native to the Caribbean, where in Spanish it is colloquially called chichí.
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.
Baridinae is a subfamily of true weevils (Curculionidae). It was established by Carl Johan Schönherr in 1836. Some 4,300 species in 550 genera are placed here, most of which occur in the New World. A few are economically significant pests, while others are in turn used for biocontrol of invasive plant pests. This subfamily also contains a few endangered species.
Hypera postica, commonly known as the alfalfa weevil, is a species of beetle in the superfamily Curculionoidea; it can be found in alfalfa fields throughout Europe. Considered a destructive threat to alfalfa production in North America, several accidental introductions have been successfully countered though the use of a variety of biological control species.
Hypera nigrirostris, commonly known as the lesser clover leaf weevil, is a species of weevil that is native to Europe and northern Africa and has been introduced to North America and Japan. Both adults and larvae feed on red clover and other plants in the family Fabaceae.
Phyllobius pomaceus is a species of short-nosed weevil commonly known as the nettle weevil.
Trichobaris is a genus of flower weevils in the family Curculionidae. There are 8 to 13 species in genus Trichobaris.
Sphenophorus parvulus, commonly known as the bluegrass billbug, is a species of beetle in the family Curculionidae. It is found in North America, especially in the eastern United States. It is a pest of Kentucky bluegrass, other grasses, corn and grain crops.
Trichobaris mucorea, the tobacco stalk borer, is a species of flower weevil in the family Curculionidae. It is found in North America.
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 wevils 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.
Listronotus oregonensis, the carrot weevil, is a species of weevil in the beetle family Curculionidae. It is found in North America.
Cylindrocopturus adspersus, the sunflower stem weevil, is a species of true weevil in the beetle family Curculionidae. It is found in North America, where the larvae tunnel in the stems of wild and cultivated sunflower plants.
Nealiolus curculionis is a species of parasitic wasp in the family Braconidae. It is a parasitoid of the sunflower stem weevil Cylindrocopturus adspersus, and a number of other species of stem-boring weevils.
The lemon tree borer, also known as the whistling beetle or the singing beetle, is a longhorn beetle endemic to New Zealand. Its larvae are generalist feeders, boring into the wood of a wide variety of trees, native and introduced. When citrus orchards were first established in New Zealand, this beetle started inflicting serious damage, and so gained the name "lemon tree borer". Four species within the genus Oemona have been identified, suggesting that more species could be found. When disturbed by predators or humans, the adult beetle stridulates creating a "rasp" or "squeak" sound by rubbing its thorax and head together against an area of thin ridges. Māori would eat a liquid called "pia manuka", which was produced by manuka trees when its wood was damaged by the larva. When Captain Cook first arrived in NZ, his naturalists, Banks and Solander, collected a lemon tree borer in their first collection between 1769-1771. This oldest collected specimen can be found in the British Museum. A few years after the first collection, the species would be first described by the Danish naturalist Fabricius in 1775.
Cosmopolites sordidus, commonly known as the banana root borer, banana borer, or banana weevil, is a species of weevil in the family Curculionidae. It is a pest of banana cultivation and has a cosmopolitan distribution, being found in all parts of the world in which bananas are grown. It is considered the most serious insect pest of bananas.
Diocalandra frumenti, commonly known as the palm weevil borer, the lesser coconut weevil, or four-spotted coconut weevil, is a species of weevil in the family Curculionidae. It occurs in Africa, Southern Asia and Northern Australia, and is a pest of coconut and other palm trees.
Myllocerus viridanus, often known as sweet potato beetle, pod borer or ash weevil, is a species of weevil native to India and Sri Lanka.
Odoiporus longicollis, commonly known as banana stem weevil or banana pseudostem borer, is a species of weevil found in South Asia and South East Asia.
