I'm new to ant keeping and I recently Caught some rather large ants the smallest being 1cm / 0.5ā to 2 cm / 1ā. Iām really doubtful any of them are queens, but still wanted to check just to be sure. They were all caught around 2:00 pm on June 6th. The first one was caught on a trail by a river and all the others were caught on the sidewalk of a street close to that river. They were al caught in Mississauga, Canada (close to Toronto). My little brother is rather hopeful of them being queens, thanks.
