Buprestis confluenta
Yellow-spotted Jewel Beetle
Buprestis confluenta is a striking metallic wood-boring beetle distinguished by its emerald green to coppery-brown coloration with dense, more or less confluent yellow flecks across the elytra. The species is primarily associated with dead cottonwood (Populus deltoides) and quaking aspen (Populus tremuloides) in central and western North America. Despite the abundance of suitable host trees in some regions, it remains uncommonly encountered and is considered elusive by collectors. Adults are typically found on large, dead, barkless cottonwood trunks.
