Emerald ash borer moves north, infested tree found in Superior
SUPERIOR, Wis. -- A Chinese insect that has killed millions of trees in the eastern United States and Canada has been confirmed in Superior.
City of Superior crews found what they thought was a suspect ash tree on Aug. 7, and after investigating further, found what appeared to be ash borer larvae in the tree. They sent samples to the U.S. Department of Agriculture in Michigan, which confirmed emerald ash borer this week.
Superior city officials made the announcement today.
