Venonat->Venomoth is based on a pun.
It's a mite evolving into a mite.
What English speakers call a mite, into what French speakers call a mite.
I know Venomoth has butterfly qualities to it, like being called Morpho while having a blue shiny, but if I had to choose between Butterfree and Venomoth on who is a moth to fit the joke, I'd say Venomoth, since the antennas Butterfree has are clearly those of a butterfly, and Venomoth has that wide, fluffy abdomen moths have.
