Horntail is known as a wooden bee as the name. It is the feature to have prickle at the tip of an abdomen by large-sized sawfly. A female makes a hole in the trunk of a standing tree or a fallen tree, and lays eggs one piece at a time, and the bacillus which rots a plant simultaneously is infected.
