The C americanus colony lost two workers so far. This specie seems to like the nest much more humid than my other Camponotus colony. I find the location that the colony settled in is a bit difficult to keep moist but they seem to keep it at a level they like by placing drops of water all around the chamber and glass. The queen laid a batch of orange eggs!
I have yet to see them eat incests but they do love filling up on water, sugar water, and fruits.
