This Atta texana colony used to be about 100 meter to the west at this road, but was poisoned in November 2020 at its former location by the highway department (see here https://www.inaturalist.org/observations/65826122), and the colony then migrated to this new location here. Migrations of texana colonies are triggered by disturbances, like natural flooding or poisoning by humans.

Unexpected here, new location for this sp! I don't remember where exactly on the trail I was when I found it
