Old London Plane Tree Seems To Be Leaking Sap And Getting Brown Stains From Higher Up

Question From: D. Allen - Rocky Ford, Colorado, United States
Q: Is there an insect that may bore into the tree and leave a sap run down the tree and kill it? I don't know what a lacebug or anthracnose or cankerstain is. We have a tree that seems to be leaking with a brown stain down from above that appears to be from something boring into it. We don't want to lose the tree because it is very old and big. Thanks Donna
