Well, actually I coined that name way back when I first started producing Hypomelanistic Miami Phase Corns. Oh yeah, I coined "Miami Phase" as well....
The reason for that name was because that particular stock came from the Miami area that I personally obtained back in the late '70s. I caught a few in the wild, and also bought a few from local mom and pop pet stores (there weren't any mega pet store chains back then) that local kids had brought in to them. I also had obtained a few individuals that had slate gray backgrounds with bright orange blotches, that came from the same area, but I don't have any idea what ever happened to that line. Haven't seen any like them for a LONG time.
