Monochamus maculosus
spotted pine sawyer
Monochamus maculosus, the spotted pine sawyer, is a longhorned beetle native to North America. It was formerly known as Monochamus mutator. Adults are attracted to monochamol, a sex-aggregation pheromone produced by males. The species breeds in stressed or recently dead conifers, with larvae tunneling in phloem and sapwood. It is a primary vector of the pinewood nematode, the causal agent of pine wilt disease.
