Thanks Again Scott Vorthmann, the Nijhout book was a GREAT SUGGESTION!! According to chapter 2, "Pattern Elements and Homologies", a proper and history-respective interpretation of colour patterns on butterfly wings should be stated in terms of the standard //Nymphalid Ground Plan//, a template invented by scientists who sought out the notion of a "general butterfly" (LOL) between 1920 and 1930. Near the distal end of the wing, in the "Occelenreihe", it is possible--depending on species--to find a line of ocelli (Latin for "eyespots"). We have recently seen such features in data sets for the pipevine swallowtail: https://www.butterfliesandmoths.org/species/Battus-philenor Except for spot number five, it appears that each ocellus is usually a union of three topological disks. One black and one white disk together form an annulus, which entirely surrounds a third orange disk. Orange connects to black along one edge, and to white along one edge. Black and white connect on two edges, separated by an orange-white edge. The color field surrounding is usually iridescent blue. Sadly, a sole black Enso is usually too simple to impress anyone, so I went ahead and designed an orange and white attachment, that fits together to form a model homologous to the above: https://0x0.st/zVxq.JPG Hmm... What is that orange marble doing in there? Well, I think it is a symbol of //unbounded curiosity//. Could it be that the orange protrusions of the pipevine caterpillar somehow metamorphose to become the orange spots of the pipevine butterfly? I hope that we can find an answer to this question soon!! Cheers, Brad
