Crioprosopus
Crioprosopus is a genus of longhorn beetles (Cerambycidae) containing approximately 13 described species. The genus Callona was synonymized with Crioprosopus in 2015, transferring six species to this genus. Species in this genus are known from North and Central America, with at least one species, C. magnificus, documented utilizing living oaks in central Mexico.

Curculionini
Curculionini is a tribe of weevils within the subfamily Curculioninae, family Curculionidae. Members of this tribe are characterized by their elongated rostrum and association with nut-bearing trees, particularly oaks. The tribe includes economically significant pests such as acorn weevils in the genus Curculio. Larval development occurs within seeds or nuts of host plants.

Cynipidae
Gall Wasps, Gallflies
Cynipidae is a family of minute wasps (1–8 mm) renowned for inducing plant galls—abnormal growths that provide shelter and nutrition for developing larvae. The family comprises approximately 1,300 described species worldwide, with major radiations on oaks (Quercus) and roses (Rosa). Many species exhibit complex life cycles involving alternation of sexual and asexual (parthenogenetic) generations, often producing morphologically distinct galls. Gall induction involves chemical manipulation of host plant tissue, with enlarged venom glands implicated in this process. The family evolved from parasitoid ancestors and represents one of the most diverse groups of gall-forming insects.

Empoa querci
Empoa querci is a species of leafhopper in the family Cicadellidae, first described by Fitch in 1851. As a member of the subfamily Typhlocybinae, it is a plant-feeding insect with piercing-sucking mouthparts. The species name 'querci' suggests an association with oak (Quercus) species. Like other leafhoppers in the genus Empoa, it likely produces brochosomes—nanoparticles that provide water-repellent and anti-reflective properties to its cuticle.

As with many cynipid wasps, detailed biological studies of this particular species appear limited in the available literature.

Nothopleurus madericus
Nothopleurus madericus is a large prionine longhorn beetle described by Skiles in 1978. It belongs to a genus characterized by robust, wood-boring beetles. The species name references Madera Canyon in the Santa Rita Mountains of Arizona, a known locality for this rare beetle. Field observations indicate adults may be crepuscular or nocturnal, with at least one individual observed in an emergence hole on oak during evening hours.

Oberea gracilis
Oak-sprout Oberea
Oberea gracilis is a longhorned beetle (family Cerambycidae) in the subfamily Lamiinae. It was first described by Johan Christian Fabricius in 1801, originally placed in the genus Saperda before being transferred to Oberea. The species is known from North America, with observations concentrated in the United States. It is commonly referred to as the 'Oak-sprout Oberea', suggesting an association with oak vegetation.

Odontota arizonica
Odontota arizonica is a leaf beetle in the family Chrysomelidae, recorded from the southwestern United States and northwestern Mexico. The species has been collected on several plant species including oaks, legumes, and ornamental plants, though its specific foodplant relationships remain incompletely known. Like other members of the genus Odontota, it likely exhibits leaf-mining larval biology.

Oneida lunulalis
Oak Gall Snout Moth, Orange-tufted Oneida Moth
Oneida lunulalis is a small snout moth in the family Pyralidae, subfamily Epipaschiinae. It occurs across eastern North America from Canada to Florida. The larvae are associated with oak foliage and galls. Adults are known by two common names: "oak gall snout moth" and "orange-tufted Oneida moth."

Ormiscus quercus
Ormiscus quercus is a species of fungus weevil (family Anthribidae) described by Schaeffer in 1906. The specific epithet "quercus" suggests an association with oak (Quercus), a pattern common in this genus. Anthribidae weevils are typically associated with fungi, often found on decaying wood or fungal fruiting bodies.

Pachybrachis diversus
Screwbean Pachy
Pachybrachis diversus is a small leaf beetle in the family Chrysomelidae, subfamily Cryptocephalinae. It belongs to a large genus of North American cryptocephaline beetles commonly known as 'scripture beetles' for their often ornate elytral patterns. The species was described by Fall in 1915 and has been collected in the southwestern United States, particularly in Arizona. Based on field observations, it appears to be attracted to ultraviolet and mercury-vapor lights in oak-juniper woodland habitats.

Paria opacicollis
oak parium
Paria opacicollis, commonly known as the oak parium, is a species of leaf beetle in the family Chrysomelidae. It was described by John Lawrence LeConte in 1859. The species occurs in North America and includes two recognized subspecies: P. o. opacicollis and P. o. wenzeli. As a member of the genus Paria, it belongs to a group of small leaf beetles often associated with woody vegetation.

Parrhasius
Parrhasius is a genus of Neotropical hairstreak butterflies in the family Lycaenidae. The genus includes the White M hairstreak (Parrhasius m-album), characterized by metallic blue upper wings and a distinctive M-shaped pattern on its silver-colored underside. Species in this genus are associated with oak habitats and have documented relationships with tending ants.

Parrhasius m-album is a small hairstreak butterfly (wingspan 32–41 mm) with metallic blue upper wings and a distinctive silver underside marked by an M-shaped pattern. Females are larger than males. The species is strongly associated with oak habitats throughout the southeastern and central United States.

Peoria floridella
Florida Peoria Moth
Peoria floridella is a small moth in the family Pyralidae, described by Shaffer in 1968. It is endemic to peninsular Florida, where it inhabits dry sandhill and scrub ecosystems. The species has been observed in association with sand live oak (Quercus geminata), suggesting a potential host relationship. Like many Phycitinae moths, it likely has a concealed larval stage, though detailed life history information remains limited.
