If there has ever been a better argument for a difference between a Butter and a Lesser, I've never seen it.
If you were to ask me, the light one is a Butter and the darker, would be the Lesser.
I know, most people say they are same, and so did I until I saw your picture. I have officially change my mind. I do think there may be 2 different morphs.
What do you think? Couldn't have a better argument than this picture.
