I now have a severe case of ANT ENVY! I wish I had a colony like yours. I have six tiny colonies of C. vicinus. They have one to three workers. The seventh queen has no eggs anymore and didn't open the cocoons of the imported brood, so she is all alone. I think I will do as you do, simply feed them honey water and termites. By the way, if you mix the honey with red food coloring, you will be able to see it in their gasters! They will have red fecal pellets, too! I have a termite colony in which I used food coloring on the wood, red, yellow, blue....so I have "rainbow termites!"
Note: I live in Southern California. Do you ever go on another ant farm site?
I love Camponotus vicinus queens.
