Epicaerus mexicanus
Brown Leaf Notcher, Mexican Root Weevil
Epicaerus mexicanus is a species of broad-nosed weevil in the beetle family Curculionidae, commonly known as the brown leaf notcher or Mexican root weevil. It is found in North America, with records from Mexico including states such as Guanajuato, Guerrero, and Oaxaca. The species belongs to the subfamily Entiminae, a diverse group of weevils often associated with feeding on plant foliage and roots.
Nemocestes
Nemocestes is a genus of weevils in the family Curculionidae, subfamily Entiminae. The genus includes at least one species, Nemocestes incomptus, a native root weevil known to feed on strawberry plants in western Washington. Members of this genus are classified within the tribe Peritelini. The genus was established by Van Dyke in 1936.
Nemocestes incomptus
Nemocestes incomptus is a native root weevil species in western North America. It is recognized as a significant agricultural pest of strawberries in western Washington, where larvae feed on plant roots. The species has been documented in California, Washington, and British Columbia.
Omileus
Omileus is a genus of broad-nosed weevils in the family Curculionidae, established by Horn in 1876. The genus contains at least one described species, O. epicaeroides. Members of this genus belong to the subfamily Entiminae and tribe Geonemini, placing them among the root-feeding weevils with characteristically short, broad rostra.
Ophryastes
Ophryastes is a genus of broad-nosed weevils in the family Curculionidae, first described by Germar in 1829. The genus contains at least 30 described species and belongs to the tribe Ophryastini within the subfamily Entiminae. These weevils are part of the diverse group of root-feeding weevils characterized by their broad, short rostrums.
Ophryastini
Ophryastini is a tribe of broad-nosed weevils (subfamily Entiminae) comprising approximately 90 species across 4 extant genera and one extinct genus. The tribe was established by Lacordaire in 1863 and has a disjunct distribution spanning North America, Asia, and Europe. Members of this tribe are characterized by their broad snouts and root-feeding habits typical of Entiminae.
Otiorhynchus meridionalis
Lilac Root Weevil
Otiorhynchus meridionalis, commonly known as the lilac root weevil, is a broad-nosed weevil in the family Curculionidae. It is a recognized landscape pest in North America, where it feeds on ornamental plants including lilac, euonymus, and peonies. The species exhibits a life cycle with root-feeding larvae and leaf-feeding adults that produce characteristic notched damage. Adults are nocturnal and occasionally enter buildings during hot weather. Native to Europe, it has established populations in western North America.
Otiorhynchus raucus
Otiorhynchus raucus is a broad-nosed weevil in the family Curculionidae, first described by Fabricius in 1777. It is a member of the large genus Otiorhynchus, which contains numerous root-feeding weevil species. The species has been recorded across parts of North America and Eurasia, with over 2,000 observations documented on iNaturalist. A former subspecies, O. r. silvicola, described from forest habitats in 1993, is now treated as a synonym.
Otiorhynchus rugifrons
Strawberry Root Weevil
Otiorhynchus rugifrons is a weevil species in the family Curculionidae, commonly known as the Strawberry Root Weevil. It is part of a large genus of root-feeding weevils, many of which are significant agricultural pests. The species has been documented across parts of North America and northern Europe. Like other Otiorhynchus species, adults are flightless and nocturnal.
Pachnaeus
broad-nosed weevils, citrus root weevils
Pachnaeus is a genus of broad-nosed weevils comprising approximately seven described species. Several species, notably P. litus and P. opalus, are economically significant pests of citrus, commonly referred to as citrus root weevils. The genus has been targeted for biological control research, with studies evaluating parasitoid wasps for management of P. litus populations.
Pachnaeus opalus
Northern Citrus Root Weevil
Pachnaeus opalus is a broad-nosed weevil in the family Curculionidae, commonly known as the northern citrus root weevil. It is native to the southeastern United States and has been documented in Alabama, Florida, Georgia, Mississippi, and New Jersey. The species is associated with citrus and related plants, where adults feed on foliage and larvae develop in roots. It was first described by Olivier in 1807 as Curculio opalus.
Sciopithes
Sciopithes is a genus of broad-nosed weevils in the family Curculionidae, established by Horn in 1876. The genus contains approximately six described species distributed in North America. Members are commonly referred to as root weevils, with at least one species, Sciopithes obscurus (the obscure root weevil), documented as a pest of strawberry crops.
Sciopithes obscurus
obscure root weevil
Sciopithes obscurus, commonly known as the obscure root weevil, is a broad-nosed weevil in the family Curculionidae. Adults are nocturnal foliage feeders that sometimes remain in vegetation during daylight hours, an atypical behavior among weevils. The species is considered an agricultural pest in the Pacific Northwest, particularly affecting rhododendrons and strawberries. Larvae feed on roots after hatching, with one generation produced annually.
Stereogaster globosa
Stereogaster globosa is a species of broad-nosed weevil in the family Curculionidae, described by Van Dyke in 1936. The species belongs to the tribe Geonemini within the subfamily Entiminae, a group commonly known as root weevils or broad-nosed weevils. The specific epithet 'globosa' refers to its rounded, globular body shape. The genus Stereogaster is part of the diverse weevil fauna of western North America.
