What's That Bug? does not endorse extermination

help!
We found this magnificent beetle on the house the other day. Ran out and grabbed these only photos of it. It was huge. Stayed quite still for it’s photo session. There’s a 5 gal bucket in one photo, as sort of a field of reference for size. The other is a closer view. We live in New Mexico in the foothills and would love to know what this bug is and a little about it if possible. Thank you so much for your help!

Hi Lisa and Ty,
This is a male Giant Root Borer in the genus Prionus. The males of the genus have the signature antennae. We tried to figure out what species this might be on BugGuide’s map page, but they listed no specific species in New Mexico, but reports of the genus in general. Then we found a New Mexico State University arthropod page that lists the California Prionus, Prionus californicus, as ranging in New Mexico. Prionus pocularis is listed in Texas. Your image lacks the necessary detail to make an exact species identification, but we would venture one of the prior two species.
