Varieties
Below is a compilation of the types I have, and others that can be found. I've borrowed better images from importers and others, until I take better pics myself. There is a bit of confusion between the 3 spotted species, white-, yellow-, and golden-spotted. I will try to clarify these more later.
Additional pictures and species can be found by clicking HERE.
