I am currently back home in Brazil and after a really strong tropical rain, I managed to save a really big ant from drowning in a pool.
Because of its large abdomen, I think it is a queen. I would love to start a colony here in Brazil as well and give it to my mother to take care of. But I have no idea about ant species at all, so I'm asking you guys for help!
She has +-2cm and I'm located in Paraná state (south Brazil).

Please also tell me if it's really a queen.
Hope I didn't save her too late and she doesn't die

Thanks a lot!
