Spruce beetle is a close relative of Mountain Pine Beetle. Spruce beetle is more of a problem on higher-elevation Engelmann spruce. See http://www.ext.colostate.edu/pubs/columngw/gr120421.html

Urban landscape spruces are at risk from engraver beetles, also called Ips beetles (Ips hunteri). See http://www.ext.colostate.edu/pubs/insect/05558.html
