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 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 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 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.
