First emerald ash borer seen in Washington

The invasive and destructive emerald ash borer has been spotted in Vancouver, the Washington State Department of Agriculture announced last week in a news release. The bright green beetles, which originate from northeastern Asia, were initially detected in the United States two decades ago in Michigan. Since then, the beetles have killed 100 million ash trees across the country.
