It's hard to say exactly. Take a look at my lesser het clown (ph ghost):
Would you say she looks like your every day lesser? No .. The dots in the alien heads are also faded with a dark outlining - typically they're a solid color. That's the biggest / strangest thing I've noticed, but even her overall color. The dorsal spots / coloration doesn't match the side pattern. Typical lessers / butters have matching colors, or it's darker - not brighter. But even just glancing at her, she reminds me of a hinting GHI influence in GHI lessers. I'm not saying she looks like a GHI lesser, but if you take a look at how the coloration in GHI lessers changes, as well as the patterning, there are similarities in HOW the colors differ (again - not saying my lesser looks like a ghi lesser, or has similar color.... just HOW the GHI influences the lesser GHI...).
