Palo Verde Root Borer

Dear Mr. Walker,
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.

  1. 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.
