I will have a few 2021 Eastern Black Kingsnakes (Lampropeltis nigra) on my table tomorrow at Doncaster. £95
They lose the white markings along their back and sides. Some individuals may still have faint markings left, but these snakes are from Louisville Kentucky, which produces the blackest darkest nigra. Here is a photo of one of my adults...Do they stay like that or turn all black ?
They are gorgeous though
