I know this is quite a few months on but I thought I'd add my experiences here just incase someone wondered the same thing.
Polyrhachis dives can and probably will cross a moat! I have had alot of trouble keeping these in the basin, even with a pump circulating the water around the moat. I have had mass breakouts and much to my amazment they have even managed to cross my room (with building supplies!) and create a nest inside an electronic alarm clock. All without my realising! I have lost alot of the colony due to them crossing the water and scaling the sides of my basin which has got a large strip of ptfe around the rim!
I think I have got them sorted out now, but I have no idea if the queen is still alive or not, but the inhabitants of the clock (a couple of hundred workers and larvae!) are now back in their home.
In conclusion, they can swim!
