The Emerald Ash Borer, a green jewel beetle native to eastern Asia that feeds on ash species, has been sighted and confirmed in a total of 26 states so far.
The Emerald Ash Borer Information Network reports that the emerald ash borer attacks ash trees in North America, as well as affecting trees in woodlots and landscaped areas. Larval galleries have been found in trees or branches measuring as little as 1-inch in diameter. All species of North American ash appear to be susceptible.
The emerald ash borer was first discovered as the cause of extensive ash tree deaths throughout southeastern Michigan in June 2002.
