Monochamus scutellatus, commonly known as the white-spotted sawyer, spruce sawyer, or spruce beetle in Alberta[1] is a common wood-boring beetle found throughout North America.[2] 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.[2] Most research done on M. scutellatus focuses on their relationship with burned forests and the logging industry,[2][3][4][5][6] with interest also being shown in their mating behaviours.[7][8][9]
