Elongate Hemlock Scale Too?!November 14, 2017
WHAT’S GOING ON IN THE FOREST?
I was out near White Lake, Sullivan County last week examining some hemlock trees. I think many are familiar with Hemlock Woolly Adelgid (HWA) & their devastating impact on hemlock trees. However, these trees were mostly absent of HWA. Instead they were riddled with Elongate Hemlock Scale (Fiorinia externa), a native of Japan. They also kill the tree similarly to HWA.
