I was wondering from peoples experiances which biome seemed to have the best chance to encounter Temple Guardians?

I believe that they all have an equal chance of having a temple guardian as I've seen them everywhere minus the Tundra.

I suggest jungle and savannah, as when I was searching for roses I encountered several. If you are wanting that reward they give, the cult building also gives big rewards like the temple guard does. I see it most at desert.

If you want to know where to find other things on islands with most success, this guide may be of use. http://beastkeeper.com/thread/5404
