White Spotted Sawyer

would like to learn more
November 13, 2009
We have found these things while camping in the rocky mountains (Wyoming) quite often. Some of them are almost three inches long with antenae. They can “sorta” fly but its pretty slow and clumsy. The white mottling seems a little bit unique to each individual.
They are nonviolent, but I cought one in my hand one time and it poked a hole in my hand, or bit me real deep (not poisonous but right into a palm tendon). It hurt for a good week. Is this a pine borer? They are neat.

Dear Interested Campers,
This is a Long Horned Borer Beetle in the genus Monochamus, most like Monochamus scutellatus, the White Spotted Sawyer.  They range over much of North America.  According to BugGuide, common hosts are Balsam fir, spruces and white pine.

  1. I was just going to say – whoever that is is very brave, as they pack a nasty bite! Cool little beetles, though 🙂

  2. Found one resembling this beetle in my house in Arlington NE. Would they be here or am i looking at the wrong one
