White worm w/ odd head
Hi. Two of these worms have come off the firewood in the last couple days, here in PA. Just wondering what they are. The picture should provide a lot of info.
Thanks!!

Flat Headed Borer Grub
Hi Diane,
This is a Flat Headed Borer Grub in the family Buprestidae, known as the Metallic Wood Borers or Jewel Beetles. You can match your photo to one we located on a Forestry Images website or to the images on BugGuide. Many of the adult beetles are quite gorgeous and are sometimes made into jewelry in tropical counties. Sadly, we are not skilled enough to tell you the exact species. Flat Headed Borers often live many years as grubs feeding on wood. We have heard reports of the Golden Buprestid, Buprestis aurulenta, emerging from furniture 50 years after it was built. You can confirm this online in numerous places including a Canadian Forestry site. We have received our own report of an adult Golden Buprestid emerging from an 8 year old pine cutting board. If your firewood is local, you have a different species of Flat Headed Borer as the Golden Buprestid is native to the Pacific Northwest.
