About the Hemlock Woolly Adelgid
The hemlock woolly adelgid (Adelges tsugae) is an aphid-like insect that covers itself with a white, waxy "wool" which acts as a protective coating. Adelgid infestations are easily recognizable by the appearance of tiny "cotton balls" at the base of hemlock needles. The "wool" is most conspicuous on the undersides of branches from fall through spring.

The hemlock woolly adelgid feeds on the sap at the base of hemlock needles, disrupting nutrient flow and causing the needles to change from deep green to a grayish green, then fall off. Without needles the tree starves to death, usually within three to five years of the initial attack. Infestations often start in large, mature hemlocks, but the insect also attacks and kills younger trees as well.

I have checked all of the hemlocks on my property and find no evidence of this pest.
