Explanation of Names
Monochamus Dejean 1821
8 spp. and 6 sspp. in the New World, all in our area(1), ~160 spp. total(2)
body ≥25 mm
Either black or mottled gray. First antennal segment has a scar-like area near the tip. Antennae of the male is twice as long as the body, about as long as the body in females.

on conifers • freshly cut, felled, dying, or recently dead trees preferred(3)
Life Cycle
Young larvae feed on the inner bark, cambium and outer sapwood, forming shallow galleries, then bore deep into the heartwood, then turn around and bore back toward the surface, forming a characteristic U-shaped tunnel with a pupal cell at the outer end.(3)
Some species are carriers of the pinewood nematode, responsible for pine wilt
M. alternatus (Japanese Pine Sawyer) of east Asian origin has been intercepted in wood crating in w.NY
The larvae are known as sawyers because of the loud noise they make while feeding(3)
