If butter pastel pin = emperor pin, then I think it makes all kinds of sense that butter pastel spider = emperor bee.

But when did morph names ever make sense?

As far as who gets to make up a morph name, generally the first person in the world to produce it makes up a name if they want. But, it is really the public that decides what sticks.

I think I already said this in the other thread, but that is a gorgeous snake!
