hahahahahahaha that is funny, only because that is not my experience at all.
Whats even funnier is, my experience is also silly.
I am first and foremost a field collector. So most that I have found were in the field. I have seen a few live ones a few dors on the road and some of my friends found more on the road(I was sleeping waiting for the next day)
So here it is, I rarely found milksnake phase in the field. In fact, only one and she was gravid. All but that one were either leonis or normal, medium wide red, and a total black one. On the road, there were more milksnake types, in fact, most were.
As are as habitat types, that becomes a odd thing. As thayeri come from oak woodland type habitats, at lower elevations, you get alterna types, and yes, they can look leonis(half bands instead of full bands) These occur on the western and southern ranges from where thayeri occur
So again it becomes a name is a name. I have not seen a milksnake type at lower alterna type habitats.
But you see all types in the oakwoodland habitats.
One funny locality is on the eastern drainage, here the milksnake types go fairly low, but there are no alterna on the eastern low elevation hills(arid). Hmmmmmmmmmmmmmmmmmmmmmmm a thinking person could go nuts hahahahahahahahahahaha.
Ok, your right, if you look at thayeri as a whole it will give you a headacke. Cheers
