About
The character 虻 is a phono-semantic compound, with the insect radical 虫 on the left providing its semantic category and the component 亡 on the right indicating its phonetic value. It refers specifically to blood-sucking flies, such as horseflies or gadflies, noted for their painful bites on livestock and humans. In classical literature, this character is occasionally used metaphorically to describe persistently annoying individuals or minor officials who drain resources from the people, extending its biological meaning into social commentary.
