Hemlock Woolly Adelgid. “Their name comes from waxy white filaments they make to protect themselves from drying out. In a heavy infestation, hemlock trees can look gray from all the “wool” on twigs and branches. They can’t fly, but are spread by wind and also hitch rides on the feet of birds, which can carry hemlock wooly adelgids for long distances. These “hemlock vampires” were first discovered in 1951 in Virginia, and by 2005 had spread to fifteen other states.
