Hi Chris,
What a stunningly beautiful specimen of a male California Root Borer,
Prionus californicus.  Your photo is the third we have received in the past week.

Hello Daniel,
Thank you so much for the identification. Amazing! We carefully put it in a cup and released it so it wouldn’t get hurt.
Thanks again

  1. Is it possible they live in Northern Michigan? I found a beetle similar to this in my basement about an inch and a half long or more. I have a picture but not great and don’t know where to post it for description
