obtusus
Agrilus obtusus is a metallic wood-boring beetle in the family Buprestidae, described by Horn in 1891. It is a specialist herbivore associated with Senna roemeriana (two-leaved senna). The species occurs in western Texas and surrounding regions of North America. Adults are small, typically collected by beating or sweeping host plants.
Agrilus olivaceoniger
Agrilus olivaceoniger is a species of metallic wood-boring beetle in the family Buprestidae, described by Fisher in 1928. It belongs to the enormous genus Agrilus, which contains nearly 4,000 described species and is considered one of the largest genera in the animal kingdom. The species is found in North America. Like most Agrilus species, it is presumed to be a twig and branch borer utilizing recently dead wood for larval development, though specific biological details for this species remain poorly documented.
