Tihu Notes | Damp Bugs and Songdu
Damp Bugs
Dormitory 156, at the eastern end of the first floor, lay always in shadow and saw the sun only a few times a year. Outside its window grew a toon tree. On it lived a very strange kind of little insect, no bigger than grains of rice, crouching all day at the roots without moving at all. Then one spring these insects suddenly swarmed into Room 156 and settled over the bedboards of a student named Cui. They could not be killed with boiling water, nor with insecticide spray, and instead gathered in ever greater numbers. Someone from that dormitory came to ask me about them. I happened to know that the Records of Tang Marvels mentions just such a creature, called the damp bug, which feeds exclusively on the yin vapors hidden in the human heart. People who have done things unfit to see the light of day are especially prone to attracting it.
