This november i caught two queens I believe are Lasius umbratus, (i'm in central Kansas) the info I've been able to find says that they usually start by infiltrating the colony of another Lasius species, but I found both of my queens in close proximity to non Lasius colonies. One queen was in a root cavity very close to a Cremanogaster colony, and one was found walking around very close to a Prenolopsis imparis colony. Now I know that this doesn't necessarily mean that they were planning on infiltrating the nests but it got me thinking that it's a possibility. As anyone tried this before? or is aware of someone that has? is there any reason why this would not work in captivity? Unless L. umbratus larvae require a specific type of care I don't see why this would not work but, maybe i'm missing something.
