Hi semery68,

Thank you for this report and these pictures. I consulted with our forest health specialist at the N. H. Division of Forests and Lands and we agree the damage pictured in image 2 is from spider mites and picture three shows spider webbing. These trees aren’t infested with either hemlock woolly adelgid or elongate hemlock scale.

Spider mites are a common pest of many trees, shrubs and other plants and not generally a problem in forested conditions.
