Insects Threaten Michigan Hemlock Trees, May Face Similar Fate as Ash Trees

Hemlock trees in Michigan face an insect threat similar to the bug that wiped out most of the state's ash trees.  WEMU's Bob Eccles has the story. 

Hemlock woolly adelgid (Adelges tsugae), commonly abbreviated as HWA, is a true bug native to East Asia that feeds by sucking sap from hemlock and spruce trees.
