Found inside an aged mesquite log in Scottsdale, AZ. What is it? What will it turn into and in how long? Pest? Affects other wood, or just mesquite? If pest, natural predators?

Flat Headed Borer Larva

Hi Sergio,
This is a Flat Headed Borer Beetle Larva in the family Buprestidae, often called the Metallic Borer Beetles or Jewel Beetles.  We believe, based on your location and the host plant, that it is Hippomelas sphenicus.  We are providing a link to BugGuide with an image of the adult beetle.  It is also pictured on the Sonoran Desert Naturalist website.
