They're about 6-8mm long but the Queen is slightly larger, but very very slight.
You'll find them in pine forests, oak forests, stream ways, decomposing leaf litter, wood piles, sometimes inside logs. They like the detritus/sand/soil mix
I found some more workers yesterday
I'm going to give this a try and see what I come up with. Right now I'd just like to find a worker. I'll worry about keeping them later but what a cool species to see!
