Hmm...interesting question. I do not know why many of the european species are so rare. It seems like many of them has been forgotten at some point, but I know several people in europe are trying to get them into their collection. However the fact is that there aren't that many avaiable anymore. I know situla can be seen in some private collections in USA, but is this not about it?
I try to get several groups/localities of the into my collection and always keep the different localities apart from eachother.
This year 2 new localities of longissimus will be added and that is usually how things seem to go every year.
At this point I also have 3 lines of situla the rest of my ratsnakes.
In my opinion the european ones like longissimus, quatuorlineata, scalaris etc can easily match any asian species.
