History: The Rainer Fesser line of North East China Dione Ratsnakes have also been coined Chinese Sun because of their selectively bred adult yellow colouration.
Notes: Dione Ratsnakes from North East China are some of the largest in captivity attaining lengths of 1.6m (pers. comm Rainer Fesser). They are also more nervous than other localities and will readily vibrate their tail when approached. They can also have very large clutches of eggs, Rainer told me that his N.E China specimens consistently have between 19-25 in a clutch.
