Agrilus obsoletoguttatus
Beech Borer
Agrilus obsoletoguttatus is a small metallic wood-boring beetle in the family Buprestidae, native to North America. It is among the smallest jewel beetle species utilized as prey by the specialist predatory wasp Cerceris fumipennis, which provisions its underground nests with paralyzed buprestid beetles. The species has been documented in nest caches containing up to 13 individuals, reflecting its small size relative to larger buprestid prey.

Anthonomini
Anthonomini is a tribe of weevils within the subfamily Curculioninae, comprising approximately 40 genera including Anthonomus, the type genus. Members are primarily herbivorous weevils, with many species exhibiting specific host plant associations. The tribe includes economically significant pests such as the boll weevil (Anthonomus grandis) and several species associated with Malvaceae, Rosaceae, and other plant families. Species are distributed across multiple continents, with documented occurrences in the Neotropics, Nearctic, Palearctic, and Oriental regions.

Anthonomus
Anthonomus is a large genus of weevils (Curculionidae) described by Germar in 1817. The genus includes numerous species, many of significant economic importance. Several members are major agricultural pests, including the cotton boll weevil (A. grandis), strawberry blossom weevil (A. signatus), and pepper weevil (A. eugenii). Conversely, some species such as A. santacruzi are utilized as biological control agents against invasive plants. The taxonomy of the genus remains under revision, particularly regarding the status of Cnemocyllus as either a distinct genus or subgenus.

Anthonomus alboannulatus
Anthonomus alboannulatus is a species of weevil in the family Curculionidae, described by Boheman in 1843. It belongs to the large genus Anthonomus, which contains numerous species associated with various flowering plants. The specific epithet "alboannulatus" refers to white annular markings, suggesting distinctive pale banding on the body. The species is rarely recorded, with minimal observational data available.

Anthonomus albopilosus
Black Toothed Croton Weevil
Anthonomus albopilosus is a species of true weevil described by Dietz in 1891. It belongs to the genus Anthonomus, a large group of weevils commonly associated with plants. The common name 'Black Toothed Croton Weevil' suggests a possible association with croton plants (genus Croton), though this relationship has not been formally documented in available sources.

Anthonomus arenicolor
Anthonomus arenicolor is a species of true weevil in the family Curculionidae, described by Clark and Burke in 2001. The species belongs to the large genus Anthonomus, which contains numerous economically significant agricultural pests. As a relatively recently described species, detailed biological information remains limited. The specific epithet "arenicolor" (Latin: sand-colored) suggests a possible association with sandy habitats or coloration.

Gonipterus is a genus of weevils in the family Curculionidae, comprising approximately 20 described species native primarily to Australia. These insects are obligate plant feeders, with many species exhibiting high host specificity. Several species, notably Gonipterus platensis, G. pulverulentus, and G. gibberus, have become significant pests of Eucalyptus plantations globally, having spread to regions where these trees have been introduced. Taxonomic confusion has historically plagued the genus, with DNA studies in 2012 clarifying that populations previously identified as G. scutellatus in New Zealand, North America, western Europe, Africa, and eastern Europe actually represent distinct species. The genus has substantial economic importance in forestry, driving research into biological control agents such as the egg parasitoid Anaphes nitens.

Listronotus maculicollis
annual bluegrass weevil
Listronotus maculicollis, the annual bluegrass weevil, is a highly destructive pest of short-mown turfgrass in eastern North America, particularly golf course putting greens, fairways, and tee boxes. Adults are small (up to 4.5 mm), dark-colored weevils with a distinct spotted or maculate pronotum. The species has expanded its range from the northeastern United States into the Midwest and Southeast since the 2000s. Larval feeding causes severe damage, with early instars acting as stem-borers and later instars feeding on the crown, resulting in irregular patches of dead turf. The weevil shows strong preference for Poa annua (annual bluegrass) over other turfgrass species, though it can develop on several cool-season grasses. Temperature, not photoperiod, drives daily activity patterns, with peak activity occurring at 14–17°C.

Toadflax stem weevil
Mecinus janthinus is a stem-boring weevil used as a classical biological control agent for invasive toadflax species (Linaria spp.) in North America. Originally introduced from Europe in the 1990s, it has established populations on Dalmatian toadflax (Linaria dalmatica) and yellow toadflax (Linaria vulgaris) in the United States and Canada. The species exhibits high host specificity, with postrelease studies in Colorado finding no evidence of nontarget herbivory on native plants even under no-choice starvation conditions. Genetic studies have revealed that M. janthinus as historically defined comprises two cryptic species: M. janthinus sensu stricto associated with yellow toadflax, and M. janthiniformis associated with Dalmatian toadflax.

Adults are black with yellowish mottled hairs, up to 6 mm long, with a short snout. Females lay eggs on thistle flower heads, which larvae enter to feed on developing seeds and flower parts, preventing seed production. While effective at controlling invasive thistles like musk thistle, the weevil was found to attack native North American thistles as well, leading to cancellation of its distribution permits in 2000.

Rhopalapion
Rhopalapion is a genus of brentid weevils characterized by an elongate body, elongate antennal club, and strong sexual dimorphism in rostrum length, with females possessing a noticeably longer rostrum.

billbugs
Sphenophorus is a large genus of weevils commonly known as billbugs, containing approximately 278 species. Several species are significant agricultural pests, particularly of turfgrass, corn, and orchardgrass. The genus is taxonomically challenging due to morphological similarity among species, especially at larval stages. Research has focused on developing molecular identification tools to distinguish species and understand their variable seasonal biology across regions.

Adults feed on thistle rosettes while larvae develop internally in stems and crowns, causing significant damage to host plants. The species has shown nontarget impacts, feeding on native Cirsium species in Nebraska and Tennessee at rates comparable to target weeds.

Triglyphulus
Triglyphulus is a genus of weevils in the family Curculionidae, subfamily Entiminae, described by Cockerell in 1906. It belongs to the tribe Byrsopagini, a group of broad-nosed weevils. The taxonomic status of this genus has been treated differently across sources, with Catalogue of Life listing it as a synonym under Trichalophus, while GBIF accepts it as a valid genus. The genus is represented by limited observations, with only 12 records documented on iNaturalist.

ambrosia beetles, xyleborine ambrosia beetles
Xyleborini is a tribe of ambrosia beetles within the subfamily Scolytinae (Curculionidae), comprising highly specialized weevils that cultivate symbiotic fungi for food. The tribe dominates ambrosia beetle faunas across Eurasia and the Americas, with the type genus Xyleborus containing over 500 species, though this genus represents an unnatural grouping of distantly related species. Many Xyleborini are economically significant invasive pests that attack healthy trees, while others are secondary colonizers of dead or dying wood. The tribe exhibits exceptional diversity with numerous genera, many of which are small or monotypic.
