There is a tree about a half mile down the road from my house that looks like it is infested with something. The tree, not being sure of the type, was alive last year, but this year there is a web-like covering over it and it appears to be dead. If it was October, I would have thought it was decorated for Halloween! Any idea what it might be and if I should be concerned? Thank you!

This looks like it could be caused by the euonymus caterpillar. In the early stage of infestation it can be controlled by a pesticide. More information can be found on canr.msu.edu and put in a search for euonymus caterpillar.
