Today I found a Camponotus snellingi colony living in a log, so I collected a larva just to see what my Camponotus floridanus colony would do with it. I put the C. snellingi larva in the outworld of my four-worker Camponotus floridanus colony, and they dragged it in the nest and now have seemed to accept it. It is in their brood pile and they are treating it like the other larvae.
If this larva eventually develops into a worker, should I worry about the C. snellingi worker possibly attacking my C. floridanus? I honestly did not really expect them to accept the larvae so easily.
