Ok, here are the eggs I saw the other night:
The eggs disappeared two days later... and tonight when I got home from work, this is what I found going on! :
Now I do not know if these are Nas D. or Nas. SP. I will try to get a pic in the daytime of just the snails. They look just like the Nas. in your first post. Even if they don't hatch, its cool to see! Thanks
