How to look for a western pine shoot borer:

Western pine shoot borer infestations can usually be diagnosed by examining the morphology of the current terminal. External symptoms of shoot borer infestations include shortened needles at the top of the terminal and reduced elongation of the shoot. The shortened needles give the terminal a clubbed appearance. Because the infested terminal does not fully elongate, lateral shoots are often longer than the infested terminal. A normal (uninfested) terminal shoot is usually 25-40% longer than lateral shoots on the same tree.
