The African's have the same blue that the scrubbies do ... definately spotable amongst the reds and rubellus (related to the latin root word rufus btw ... rufus is red ) Curious that your worms ran to the edges, and you noticed that it was wos down to crappy manure. What made it crappy? (The manure?) ... that is something to know. Good on you for being so brilliantly part of the community, such that you got a listing with your local council!
