Cottonwood Borer

Insect Identity
I found this particular insect in my garage this evening and I’m not sure what it is. Can you help me identify it? Thanks in advance for your assistance.

Hi Glenn,
This magnificent beetle is a Cottonwood Borer, Plectrodera scalator. Its unique appearance assures that once identified, it will not be confused with any other North American insect. The larvae of the Cottonwood Borer bore into the wood of poplars and willows, generally near the base. Adult beetles eat young shoots from the host tree.
