Monochamus scutellatus, commonly known as the white-spotted sawyer, spruce sawyer, or spruce beetle in Alberta is a common wood-boring beetle found throughout North America. Adults are large-bodied and black, with very long antennae; in males, they can be up to twice the body length, but in females they are only slightly longer than body length. Both sexes have a white spot on the base of the wings, and may have white spots covering the wings. Both males and females also have a spine on the side of the prothorax. Most research done on M. scutellatus focuses on their relationship with burned forests and the logging industry, with interest also being shown in their mating behaviours.
