Interesting
Does anyone have any theory on why? Genetic, disease, fungus, pupa was pressed up against something? I'm guessing a fungus under the elytra is showing through, and may actually be spreading to the "good" side near the top. (Just trying to get discussion started by giving people something to contradict)
BTW - I think the extra brown stripe on the "good" side leads to False.

Somatic mutation?
Somatic mutation?
I think that there are cases in which each side is of a different sex and things like that. Yes, it would be interesting to know more about this.
