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.

I had a Lasius murphyi queen that I refridgerated and dropped in with some Formica sp workers and brood. Kept them together in the fridge for 24 hours and then took them out and within an hour the queen was dead.

I guess it would be a simple experiment to perform but you're probably not going to get good results. If you want to really start a colony with them it's probably best to just use Lasius. Definitely read this thread if you haven't. I don't believe any other species outside the genus Lasius have been observed as hosts.

i've read it and i've also read the paper talking about founding various temporary social parasites. from the evidence given in the paper It seems to me that the queens are not very combative (at least with the workers) so i was thinking callow workers from any species should work, since they would not reject her. But Idk, this is mostly a back up plan in case i can't find a lasius colony.
