Thank you very much Neil. I read somewhere that these longhorn beetles are sometimes attracted to paint. I wonder if this one is attracted to creosote? I even placed a limb with leaves in front it to climb on but it didn't want anything to do with it. It just wanted to stay on the pole.

This is a really awesome beetle. Mark's right with "anti-camo"! Cheers for the video too. It was interesting.

No doubt Tukup. I didn't think it was real when I first spotted it.

Black and white can sure be "colorful" can't it? Nice catch Brian. Thanks
