While exploring around Mt. St Helens, I found this interesting beetle, Buprestis aurlenta, from what I can tell. But I am no expert. I just love the amazing array of colors. However, this species is the most damaging in its genus. Larvae have been known to take 30 years to complete their development in structural timbers. The emergence holes sometimes penetrate roofing materials which results in leakages. For example, Orpheum Theater in Vancouver was water damaged after "bargain priced" roofing timbers, cut from trees salvaged from the Taylor River fire on Vancouver Island, produced a large number of adult beetles which bored straight through the tar roof.
