I'm wondering where this extra stroke came from in the kanji for cicada that I have highlighted and would like an explanation since it doesn't match up with the kanji radicals on kanshudo
https://www.kanshudo.com/word/%E8%9D%89/1387080?oq=%E8%9D%89
Does that line have to match up with the Kanji radicals?
The whole left part is a radical (むし) and its origin seems to be a visual transcription of a snake, according to Wiktionary. https://en.wiktionary.org/wiki/%E8%99%AB
I'm sorry, if I didn't get your question right, I'm still new to all of this.
