After nearly ten years, we are finally having our house built. It's only in the framing stage, but we're so excited that we were crawling all over it this week-end. I spotted this fellow on one of the studs. The body, not counting the length of the legs, was about 1-1/4" long. The antennae are reddish, but the interesting part was the the toothed keel on its back. I haven't been able to ID it. Anyone know what it is?
