Did you know that EAB has been in the U.S. for decades? The East, Midwest, and Lake States are being devastated by Emerald Ash Borer. See the latest from Wisconsin: https://doorcountypulse.com/photosynthesis-emerald-ash-borer-trails/ This is a great pic of the damage caused by larvae of the borer.
Colorado can expect to see a continuation of the movement of this beetle.
