I heard from a reliable source that all the S. heros color forms are all the same species. So I attempted to fire a mating with the two tonight. They stayed in the position you see in the pic for about 30 minutes. Then the female finally turned away. How do I know male from female? I had some that laid eggs last year. Other than that, I'm just speculating and looking at behavior, don't really know for sure. Anyway, I thought it might be a very long night. Maybe next time. And maybe time to find more S. heros heros to exp with!! I have a lot more S. h. castaneiceps than I do S. h. heros.
