Duan Yucai showed his confusion about mián(蝒) and fán(蠜), believing that someone mixed up the two insects. In Shuo Wen
people regarded fùfán(阜蠜) and fán(蠜) as the same insect and Mr. Duan thought that fùfán(阜蠜) was also called fùzhōng(阜螽) in Er Ya
, but the problem was that fùfán(阜蠜) was caozhōng(草螽). Caozhōng(草螽), together with fùzhōng(阜螽), is one of the five insects in Er Ya.
As a result, what insect mián(蝒) or fán(蠜) refers to in Shuo Wen
has been an unsolved puzzle for over 2000 years. After further textual research, the essay comes to the conclusion that: the scientific name for mián(蝒) is zhaoma(灶马), the zhaojimu (灶鸡母) in Shu dialect; Fán(蠜) is similar to xishuai (蟋蟀), the former is youheshang(油和尚) or heshangtouer(和尚头儿) while the latter is zhaojizi(灶鸡子) in Sichuan dialect.
