Recently got back from a trip to the North Shore area of MN. We were hiking the SHT and found two insects that we weren’t able to ID on 6-25-11
The second is a long-horn beetle. He was the largest long-horn I’ve ever seen. Body about 2-3 inches in length. Each antenna about 6 inches.
Thanks again! I

White Spotted Sawyer

Hi again Heather,
The white triangular patch where the wings meet, known as the scutellum, is a distinctive marking of the White Spotted Sawyer,
Monochamus scutellatus.  Your individual is a male.  Males have significantly longer antennae.

    We have purchase a pine log bed –recently made, it appears that these bugs are coming out of the bed…. what do we do? How do we stop them?

      If the larvae were present in the wood when the bed was constructed, there is nothing you can do but to let the adults emerge. They will not lay additional eggs in the finished bed. Only the larvae that were present prior to the wood being milled will develop within the finished piece of furniture.
