Jewel Beetle

Dear John,
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?

Hi, Daniel.
Sorry, I wouldn’t have known the tree type but I do have footage of the beetle probing about the wood.Metallic Borer or Jewel beetle – are they bad?
I ask because this photo was taken at a lake where hundreds of dead trees have been cut down apparently due to a beetle invasion
Thanks all the same.
John
Daniel,
I looked about for the beetle responsible for tree deaths at the local lake. It’s a bark beetle.
Although the beetle’s destruction of trees may not be a terrible thing?
Hello again John,
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.

  1. It looks a lot like Buprestis (Buprestis) consularis, but may be not on its range?
