Monochamus scutellatus
''Monochamus scutellatus'', commonly known as the white-spotted sawyer or spruce sawyer,〔(Spruce sawyer ), Insects of Alberta〕 is a common wood-boring beetle found throughout North America.〔Raske, A. G. (1972). Biology and control of ''Monochamus'' and ''Tetropium'', the economic wood borers of Alberta (Coleoptera: Cerambycidae). ''Northern Forest Research Centre Internal Report'', Canadian Forestry Service, Edmonton, AB〕 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,〔〔Saint-Germain, M., Drapeau, P., and Hebert, C.

==Life history==
Adults feed preferentially on members of the pine and spruce families for up to seven days after emerging between mid-June and mid-August. After mating, females chew small egg niches into dead or dying trees or logs, into which they deposit one egg each.〔 Both sexes mate repeatedly with different partners, and females have been found to lay between 15 and 20 eggs on average per lifetime.〔 Once the larvae hatch, they burrow into the phloem and to the cambium, where they continue to feed until emergence. Life cycles ranging from one to four years have been recorded in different areas and specific habitats.〔 About one week after pupae formation, adults emerge from their larval log by chewing through the bark.〔
