This is a Palo Verde Root Borer, and they generally begin to appear in late June.  The larvae bore in the roots of the Palo Verde tree.

    We rescued a Palo Verde Root Borer Beetle out of our pool this evening. Now my boys want to keep him as a pet. Any idea what the adults eat? Are they safe to keep? They boys won’t be holding him, just observing.

      You might try the foliage of the Palo Verde. We are uncertain of the diet of adults. They may live off of stored fat accumulated as a grub.
