[1][3][4] Carebara diversa is a eusocial insect and individuals have continuous allometric variation in size and morphology to facilitate task allocation and partitioning of work.
For example, small, young, minor workers specialize in caring for the larvae but extend their activities as they grow older.
These ants regularly form long columns for foraging and sometimes roof these trails with arcades constructed of soil particles.
One study showed that 94% of individuals failed to cross an obstacle in the foraging path and that eventually the column creates a detour around such obstructions.
[citation needed] Carebara diversa is widely distributed from India through Southeast Asia to Taiwan and the Philippines.
Specimens taken at the Camp Zama U.S. Air Force base in Kanagawa Prefecture are believed to have originated from commercial introduction from Southeast Asia.
