White fuzzy tree branch bugs - Grylloprociphilus imbricator

White fuzzy tree branch bugs - Grylloprociphilus imbricator
Kingsville, Baltimore County, Maryland, USA
September 30, 2007
Size: Small
I have a cluster or 6 trees in my front yard and thousands of these little white fuzy bugs were only on 1 branch. I thought it was fuzz at first till I looked closer. Their bodies are very small with long white fuzzy haie sticking out of it and all the do is rock back and forth. What are they somebody help me please.

The tree is American Beech (Fagus grandifolia), I believe this is the beech wooly aphid (Grylloprociphilus imbricator), commonly found in large numbers on the twigs and sometimes the leaves. (Phyllaphis fagi) an introduced species is found on planted European Beech, and usually on the backsides of leaves.

Does this insect kill the tree? Is there a treatment?

 
Fact sheet
If you followed the link to the fact sheet in the comment right next to yours, you would see that "there is no indication that this aphid causes any real serious harm beyond that of the vast amounts of aesthetically displeasing sooty mold."
