This species is remarkable for its habit of killing live trees. 

 It encases the trunk, for a distance of 8 feet from the ground, 

 with a thick crust of earth ; under cover of this crust it eats 

 through weak spots in the tree to the heart of the wood, which i 

 excavates, forming there a kind of nest built of wood-fibre.
