Hemlock Trees

Nicholas A. Tonelll

There’s a new invasive insect causing problems in Onondaga County. The hemlock woolly adelgid has started feeding on hemlock trees in the watershed that provides water for the city of Syracuse.

An alert arborist found the bug that’s been on the eastern seaboard since the 1950s, munching on hemlock needles in trees on the Onondaga County side of Skaneateles Lake.
