Biology

A colony from Bandong was found running in file during the late afternoon in midmountain rain forest. The workers wer carrying brood consisting of half-grown larvae; thus the colony is interpreted as being in the nomadic phase. Three Pheidole soldiers, representing at least 2 species, were retrieved from the mandibles of the the workers. (Wilson 1964)

Castes

Known only from the worker caste.
