Described by Charles Henry Blake Patton in 1879, the species exhibits pronounced sexual dimorphism; while females are shiny and black, males are densely covered in striking golden or brownish hair. Like other carpenter bees, they excavate tunnels in dead wood or structural timbers to build their nests. They are important pollinators for various local flora, including trees and agricultural crops.
