well specific locals of leachies and chahoua? no. and actually, they mostly inhabit different areas, and only over lap a little. its not like they all come from the same place. and i would think, that in the wild, where there are thousands of your same species, there would be no reason to mate with something from a different species. and if they did cross in the wild, since crosses are fertile, someone at somepoint probably would have found one.
