One interesting detail about Venomoth is that for some reason for the release of Red and Blue in the US, Sugimori made artwork depicting Venomoth was yellow spots on the back of its wings which some associate with Caterpie's yellow circles along its body. When the Gold & Silver Spaceworld build leaked, it was discovered that Venomoth's beta sprite also had the same spots on its wings. The fact it was the US artwork is what's so confusing though because it already had a finalized design years earlier.
