Agrilus langei
Agrilus langei is a species of jewel beetle in the family Buprestidae. Like other members of the hyperdiverse genus Agrilus, it is a metallic woodboring beetle. The genus contains nearly 4,000 described species and is perhaps the largest genus in the animal kingdom. Most Agrilus species are twig and branch borers that develop in recently dead wood, though some attack living trees. The specific biology and host associations of A. langei remain poorly documented.
Agrilus lautuellus
Agrilus lautuellus is a species of metallic wood-boring beetle in the family Buprestidae, described by Fisher in 1928. The species is found in North America. Based on field observations, adults have been collected from Diospyros texana (Texas persimmon) foliage in west Texas, where they were observed sitting on leaves in the manner typical of many Agrilus species. Like other members of the genus, it is presumed to develop as a larva in recently dead wood of its host plant, though larval biology remains unconfirmed.
Agrilus lecontei celticola
Agrilus lecontei celticola is a subspecies of jewel beetle in the family Buprestidae, described by Fisher in 1928. The subspecies is associated with hackberry (Celtis spp.) as a larval host. Its taxonomic validity has been questioned, with evidence suggesting it transitions broadly across Louisiana and Mississippi with the nominate subspecies A. lecontei lecontei, making subspecific identification of specimens from eastern regions problematic. The subspecies has been recorded from Texas and Oklahoma.
Agrilus mimosae
Agrilus mimosae is a metallic wood-boring beetle in the family Buprestidae, described by Fisher in 1928. The species is distributed across Central America and North America. As a member of the hyperdiverse genus Agrilus, it is presumed to be associated with woody plants, though specific host relationships and biological details remain undocumented in the available literature.
Agrilus oblongus
Agrilus oblongus is a species of metallic wood-boring beetle in the family Buprestidae, described by Fisher in 1928. It is native to North America. As a member of the hyperdiverse genus Agrilus, which contains nearly 4,000 described species, it shares the general characteristics of small size and metallic coloration typical of jewel beetles. Specific biological details regarding its host plants, larval habits, and distribution within North America remain poorly documented in published literature.
Agrilus obolinus
Agrilus obolinus is a metallic wood-boring beetle in the family Buprestidae, described by LeConte in 1860. The species occurs in Central America and North America. Like other members of the genus Agrilus, it is presumed to develop as a larva in woody plant tissue, though specific host associations and biological details remain poorly documented. The species has been rarely encountered in collections, with only two iNaturalist observations recorded.
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.

It is among the most visually striking species in its genus, with males exhibiting bronzy-brown and brassy coloration while females are uniformly blue to greenish-blue. Adults are active during late summer and early fall, an unusual seasonality for wood-boring beetles in this region. The species is strongly associated with gray rabbitbrush (Ericameria nauseosa), which is presumed to serve as its larval host despite the absence of confirmed rearing records.
Ampheremus cylindricollis
Ampheremus cylindricollis is a species of metallic wood-boring beetle in the family Buprestidae, described by Fall in 1917. The genus Ampheremus is part of the diverse Buprestidae family, commonly known as jewel beetles, characterized by their often brilliant metallic coloration. This species is recorded from the Nearctic region of North America. The specific epithet 'cylindricollis' refers to the cylindrical shape of the pronotum (the segment behind the head).
Anambodera
An undescribed species of jewel beetle in the genus Anambodera, collected from Nothing, Arizona. The specimen resembles A. gemina but differs in multiple characters including coarse elytral punctation and heavily sculptured, bronzed pronotal surface. The genus Anambodera is restricted to western North America and is poorly represented in collections due to cryptic habits; most species do not visit flowers but instead alight on rock surfaces or bare soil. The genus is currently undergoing revision by Dennis Haines and George Walters.
Anambodera lucksani
A small jewel beetle in the family Buprestidae, described by Walters in 1982. The genus Anambodera is restricted to western North America and is closely related to the diverse genus Acmaeodera. Species in this genus are poorly represented in collections due to their cryptic habits.
Anambodera nebulosa
Anambodera nebulosa is a small metallic wood-boring beetle in the family Buprestidae. The species is found in western North America and is characterized by its cryptic habits, typically occurring on rock surfaces or bare soil rather than flowers. It was described by Horn in 1894 and is one of several species in the genus Anambodera, which is restricted to western North America and remains incompletely known taxonomically.
Anambodera santarosae
Anambodera santarosae is a species of jewel beetle in the family Buprestidae, first described by Knull in 1960. It belongs to a small genus of western North American buprestids that are morphologically similar to Acmaeodera but distinguished by several structural characters including non-reflexed epistoma, rounded pronotal angles, and visible suture between abdominal sterna. Species in this genus are generally poorly represented in collections due to their cryptic habits.
Anthaxia carya
Anthaxia carya is a metallic wood-boring beetle in the family Buprestidae, described by Wellso and Jackman in 2006. It belongs to the subgenus Haplanthaxia within the genus Anthaxia. The species is found in North America. Like other members of the genus Anthaxia, it is associated with woody plants and exhibits the characteristic metallic coloration typical of jewel beetles.
Anthaxia caseyi
Anthaxia caseyi is a metallic wood-boring beetle in the family Buprestidae, native to North America. The species was described by Obenberger in 1914 and includes four recognized subspecies. Field observations indicate adults are flower visitors, particularly associated with Purshia standsburyana (Stansbury's cliffrose) and other flowering plants in western North American habitats.
Anthaxia caseyi caseyi
Anthaxia caseyi caseyi is a subspecies of jewel beetle in the family Buprestidae. Based on field observations, adults have been collected from flowers of Purshia stansburyana (Stansbury's cliffrose) in the southwestern United States. The nominate subspecies occurs in the western Nearctic region. Taxonomic study of populations in Utah and Arizona suggests potential subspecific variation that may not align with currently recognized subspecies boundaries.
Anthaxia caseyi pseudotsugae
Anthaxia caseyi pseudotsugae is a subspecies of jewel beetle (family Buprestidae) described by Chamberlin in 1928. It is distinguished from the nominate subspecies A. c. caseyi by its dark coloration rather than bright green.
