I finally managed to catch a queen ant and keeping it in a lunchbox container (couldn't find a tube setup in time). I would show you some pictures, but don't really want to disturb her right now. Caught it in Sydney, Australia. It's black, about 6-7mm long.
I see there are some white eggs (I guess those are eggs) next to it now, she keeps moving them around her, nothing else really.
Does anyone know what is the approximate time for them to hatch? Is there anything I should do to help, or best to just leave her alone? I left a wet cotton bud there for her, some bread which then got covered in mould, so I took it out. The container is pretty big for 1 ant, but moving it to a tube isn't an option now I don't think.
Happy to hear any ideas, it took me a very long time to even catch one!
