Spotted Pine Sawyer

Description:

Monochamus clamator is a long-horned beetle. The larva bores into dead and dying trees.

Habitat:

Spotted near Mazama, WA. Open pine and fir forest.

Notes:

If sawyer beetles infect freshly cut pine logs, they can cause a 30–40% loss in value due to the tunnels their larvae bore. It's important to process logs within a few weeks of cutting or store them in water to minimize damage. Some species are known to transport phoretic Bursaphelenchus nematodes, including B. xylophilus which causes pine wilt disease.
