Your letter to the bugman: Bugman, I spotted this large-ish beetle on a fallen tree, sticking its ovipositor in crevices in the wood. What is this bug?

This is a Metallic Borer Beetle or Jewel Beetle in the family Buprestidae, but we are not having any luck determining a species for you. Do you know what type of tree you sighted it upon?
You are correct. The Bark Beetles are responsible for the tree die-off. Jewel Beetles have larvae that bore in wood, but they are rarely numerous enough to create a problem.
