So who knows knows about bugs? I have an infestation of these guys all over the only tree in my yard. This is the first year that I've ever noticed them. Coincidentally, this year the tree decided to not sprout and looks dead. I know Matt, I'm a tree killer. My thought is that the bug killed or diseased the tree and that's why it looks or is dead. Any ideas what the bug is or if it did harm the tree? Note: there are two bugs in this picture. It appears I now am into bug porn.
