How common are Scolopendra polymorha with ornage head and tail?

[DubiaW]

I have been planning to go out looking for S. heros in the desert around my house. My wife caught a centeped outside that had an orange head and tail with a blue tinted body. I eventually identified it as S. polymorpha but it sure looks like a little hero. How common is this morph in the trade?

Here in Italy they are rare (S.polymorpha) just like rare are S.heros :-/
