Spruce beetle (Dendroctonus rufipennis)

If you haven’t seen me yet, you soon will. As temperatures start to rise you’ll see my small reddish brown to black cylindrical body (1/4" long by 1/8" wide) as I look for a new home in a nearby spruce tree. http://alaskasprucebeetle.org

Have you noticed red sawdust at the base of a tree? This is the result of spruce beetles boring into trees-other insects also bore into trees, you may be able to id the type of beetle by sawdust color & location.
