Found in Northern California, Bay Area (near San Francisco)
Up in the hills, at the campus of College of San Mateo
Was pretty cold out, but around summer, before fall semester.
I think it’s just some kind of beetle, but I wanna know exactly what kind. It was about 2 and a half inches long, and 1 wide.
This is a Ponderous Borer, Trichocnemis spiculatus, which according to BugGuide is also known by the names “Pine Sawyer, Western Pine Sawyer, Spined Woodborer, and Ponderosa Pine Borer.” The large grubs bore into the wood of the Ponderosa Pine.
