Life History. 
This beetle tunnels into the heart-wood of blue pine and 
spruce. The insect enters the tree from outside by boring a 
tunnel, which may go horizontally into the wood (in standing 
trees) or may be at an angle. On reaching the wood, they 
usually mine out a gallery at an angle to their entrance one. 
This latter tunnel may be straight or may wind about [see
