Huaca
Huaca is a genus of weevils in the family Curculionidae, described by Carl Johan Schoenherr in 1833. The genus belongs to the hyperdiverse weevil family, one of the largest families of organisms with over 40,000 described species. As a historically established genus in early coleopteran taxonomy, Huaca represents part of the 19th-century effort to classify the immense diversity of Neotropical weevils. The genus is currently accepted in modern taxonomic catalogs, though specific species-level diversity and biological details remain poorly documented in accessible literature.
Huaca apian
Huaca apian is a species of true weevil in the beetle family Curculionidae. It was described by Clark in 1993. The species is known to occur in North America. As a member of Curculionidae, it possesses the characteristic elongated rostrum typical of weevils.
Hylobiini
Hylobiini is a tribe of weevils within the subfamily Molytinae (Curculionidae). The tribe includes approximately 89 species in the genus Heilipus, which are distributed across the Americas. Members of this tribe are primarily associated with the plant family Lauraceae, with some species functioning as seed predators in fruits and others as bark-boring pests. The tribe contains three subtribes: Epistrophina, Hylobiina, and Incertae sedis.
Hylobius
pine weevil, large pine weevil
Hylobius is a genus of true weevils (Curculionidae) containing approximately 15 described species. Several species, particularly Hylobius abietis and H. pales, are significant forestry pests that damage coniferous trees through root and collar feeding. The genus is distributed across the Northern Hemisphere, with species occurring in North America, Europe, and Asia. Adults are mobile and capable of flight, while larvae are relatively immobile and develop in soil near host roots.
Hylurgops subcostulatus
Hylurgops subcostulatus is a species of weevil in the family Curculionidae, originally described by Mannerheim in 1853. The species is currently treated as a synonym of Pachysquamus subcostulatus, representing a taxonomic reassignment to the genus Pachysquamus. It is recorded from North America and Middle America. As a member of Curculionidae, it belongs to one of the largest families of beetles, commonly known as snout beetles or true weevils.
Hypera
clover weevils, alfalfa weevils
Hypera is a large genus of weevils in the family Curculionidae, tribe Hyperini, containing at least 280 described species. The genus includes several economically significant agricultural pests, notably the alfalfa weevil (Hypera postica), which is the most problematic insect pest for alfalfa growers in the western United States. Species in this genus are associated with leguminous host plants, particularly clovers (Trifolium spp.) and alfalfa (Medicago sativa).
Hypera brunnipennis
Egyptian alfalfa weevil
Hypera brunnipennis, commonly known as the Egyptian alfalfa weevil, is a true weevil in the family Curculionidae. It is a significant agricultural pest of alfalfa (Medicago sativa) in certain regions, particularly in parts of the Middle East and North Africa. The species has been subject to biological control research focusing on its natural enemies, including parasitoid wasps and predatory insects. Its scientific name is frequently misspelled as 'brunneipennis' in the literature.
Hypera compta
Hypera compta is a species of true weevil in the family Curculionidae. It was described by Say in 1832. The species is currently treated as a synonym of Hypera rumicis in some taxonomic databases, though both names appear in literature. It is recorded from North America and has also been reported from Belgium. Very little is known about its specific biology or ecology.
Hypera diversipunctata
Hypera diversipunctata is a true weevil in the family Curculionidae, first described by Schrank in 1798. The species has a Holarctic distribution, occurring in both North America and Europe.

The genus Hypera includes several agriculturally significant species, though specific ecological details for H. diversipunctata remain poorly documented.
Hypera eximia
Hypera eximia is a weevil species in the family Curculionidae distinguished by its rare surface swimming behavior, an unusual adaptation among weevils. This behavior has been documented and studied for its morphological and phylogenetic implications within the genus Hypera. The species is poorly represented in observation databases, with only four records on iNaturalist. It has been synonymized under the genus Apodrosus as Apodrosus eximius in some taxonomic treatments.
Hypera paludicola
Hypera paludicola is a species of weevil in the family Curculionidae, described by Tuttler in 1973. It belongs to the genus Hypera, which contains several species associated with leguminous plants. The specific epithet 'paludicola' suggests an association with marsh or wetland habitats.
Hypera rumicis
Dock Hyper Weevil
Hypera rumicis is a small true weevil in the family Curculionidae, known as the Dock Hyper Weevil. The species is native to Europe and has been introduced to North America. It is a specialist herbivore associated with dock and sorrel plants (Rumex spp.), where both larvae and adults feed on host tissues. The species has been investigated as a potential biological control agent for invasive Rumex weeds, though it can also cause damage to crops. Adults show complex behavioral responses to plant volatile compounds, with attraction and repellency depending on concentration and mating status.
Hyperinae
Cocoon Weevils
Hyperinae is a subfamily of true weevils (Curculionidae) whose larvae are notable for constructing silk cocoons for pupation, earning them the common name 'Cocoon Weevils.' Larvae of some species exhibit unusual social behaviors, including coordinated processionary movement and chemical trail-following—traits convergent with social caterpillars but rare among beetles. The subfamily's taxonomic placement has been debated, with some species historically classified under Molytinae. Host plant associations include Malvaceae and Ericaceae, with the latter representing a newly documented host family for the group.
