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 limpiae
Agrilus limpiae is a species of metallic wood-boring beetle in the family Buprestidae. It was described by Knull in 1941 and is native to North America. The species is a specialist on soapberry (Sapindus drummondii), with adults collected from foliage of this host plant. It is one of many Agrilus species that exhibit host-specific relationships with particular tree or shrub species.
Agrilus macer
Large Hackberry Agrilus
Agrilus macer is a metallic wood-boring beetle in the family Buprestidae, primarily associated with sugarberry (Celtis laevigata) in the southeastern United States. The species is considered a secondary pest that attacks dying or declining host trees at high densities, with egg masses deposited on trunks, branches, and exposed roots. Despite intensive colonization of weakened hosts, it does not appear to transmit harmful fungal pathogens or act as a primary cause of tree mortality.
Agrilus malvastri
Agrilus malvastri is a metallic wood-boring beetle in the family Buprestidae, described by Fisher in 1928. It is one of the few North American Agrilus species documented as routinely visiting flowers, specifically those of Sphaeralcea (globemallows). The species occurs in Central America and North America, with records from the southwestern United States including New Mexico, Utah, and Arizona. Unlike most Agrilus species, which are associated with woody plants, A. malvastri appears to be associated with herbaceous plants in the family Malvaceae.
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.

The species is documented from North America and has been collected from hackberry (Celtis spp.) in Oklahoma. Like other members of its genus, it is presumed to have larvae that tunnel in woody host plants.
Agrilus parkeri
Agrilus parkeri is a species of metallic wood-boring beetle in the family Buprestidae, described by Knull in 1935. It is distributed across Central America and North America. Like other members of the genus Agrilus, it is a wood-borer with larvae that develop in plant tissue. Specific biological details remain poorly documented in published literature.
Agrilus parvus parvus
Agrilus parvus parvus is a subspecies of jewel beetle in the family Buprestidae, one of the most diverse genera in the animal kingdom. As with other members of Agrilus, it is a wood-boring beetle whose larvae develop in plant tissue. The nominate subspecies occurs across multiple biogeographic regions including the Nearctic.
Agrilus planipennis
Emerald Ash Borer, EAB
Agrilus planipennis, the emerald ash borer, is a highly destructive invasive beetle native to northeastern Asia. First detected in North America in 2002 (Michigan) and European Russia in 2003, it has since spread to 36 U.S. states, five Canadian provinces, and across Eastern Europe. The species has killed hundreds of millions of ash trees, causing severe ecological and economic damage. In its native range, it occurs at low densities without significant tree mortality; in invaded regions, it typically kills over 90% of ash trees within 2–4 years of establishment.
Agrilus politus
willow gall limb borer, common willow agrilus
Agrilus politus is a metallic wood-boring beetle in the family Buprestidae. The species is commonly known as the willow gall limb borer or common willow agrilus. It is associated with willow (Salix) hosts and has been documented as part of the prey provisions collected by the crabronid wasp Cerceris fumipennis. The species occurs in Central America and North America.
Agrilus politus politus
Agrilus politus politus is a subspecies of jewel beetle in the family Buprestidae. It belongs to the hyperdiverse genus Agrilus, which contains nearly 4,000 described species and may represent the largest genus in the animal kingdom. Like most Agrilus species, A. politus politus develops as a larva in woody plants. The species has been documented in the central United States, with records from Oklahoma and Missouri.
Agrilus prionurus
Soapberry Borer
Agrilus prionurus, commonly known as the soapberry borer, is a metallic wood-boring beetle in the family Buprestidae. The species is native to North America and Central America. Like other members of the genus Agrilus, it is presumed to develop as larvae in wood, though specific biological details remain poorly documented. The common name suggests an association with soapberry plants (Sapindus), but this relationship has not been rigorously confirmed in published literature.
Agrilus pulchellus
Beautiful Fleabane Root-borer
Agrilus pulchellus is a species of metallic wood-boring beetle in the family Buprestidae. It is found in Central America and North America, with records from the southwestern United States and Mexico. The species is associated with fleabane (Erigeron) as a host plant, as indicated by its common name. Like other Agrilus species, it is a wood-borer whose larvae develop in plant roots or stems.
