In case it's not clear, that's just the kanji for "egg" and "bug"

(torn between this and insectoeuf, but I think having the entire "insecte" word in there is the better choice)

but I also have another... suggestion for French

Coquecinelle

_{Yes I know it's the chickens that lay eggs, not the roosters
I actually mean the "shell" bit, hence coque and not just coq
Don't think too much about it}
