These ants have basically two kinds of workers. The minor ants are small uniform-sized ants that gather food, tend and feed the queen and larvae, clean and build the nest among other tasks.
The majors are variable in size and have larger bodies and disproportionately large heads. They spend a fair amount of their time cleaning their own bodies. They also defend the colony and food stores, and crush seeds.
If the ratio of minors and majors changes so that there are fewer minor workers, the majors will fill in for minor worker ant jobs including caring for young and cleaning the nest.
