Description of specimen

Very shiny green bug I'd never seen before flew into my fed ex truck while I was working

Commentary

This is western cedar borer, only attacks already dead and dying redcedar. It is native. Please see this emerald ash borer fact sheet which shows some common look-alikes: http://www.oregon.gov/ODF/ForestBenefits/Pages/ForestHealth.aspx
