Arthur and Jamey found this bug and tried to describe it to me a few days ago. But I had no frame of reference because I'd never seen this before.
Yesterday Arthur spotted this one and called me over to see it.
I can't wait to learn about this one.
UPDATE: as usual I wait to do my research until after I post.
I found out that this insect is native to North America (after fearing the worst when I cam across the Asian Longhorned Beetle in my search). It turns out they like to use dead wood to raise their young, and aren't considered economically damaging. Whew!
