I didn’t see this one. I live in Memphis, TN and found this crawling up the wall in the bathroom (Yeecch!). I think it flies, I’m not sure. It made a strange noise when I was putting the top of a "side salad" plastic lid over it to capture it without crushing it. Perhaps it was trying to tell me it didn’t like what was going on. Intrigued by the markings on the posterior, but have no clue at all what it is. Can you help ?
This is the Ivory Marked Beetle, Eburia quadrigeminata. Larvae bore in the heartwood of ash, hickory and other hardwoods, and adults can emerge years after milling.
