Carebara

also known as marauder ants. Most Carebara are small, cryptic, hypogaeic ants that nest in the soil, the leaf litter or in termite mounds. Some species show an extreme size dimorphism between the tiny worker and the very large queen caste.

Division of labor is correlated with these size-related morphological differences, and with the age of individual workers; for example, younger minor workers specialize in carrying for the larvae, but extend their activities as they grow older.
