Oligomyrmex sp. ??? Small Ants
Major and minor workers of an Oligomyrmex species. Minor workers of Oligomyrmex are among the world's smallest ants. The ants pictured here, like many tropical rainforest insects, belong to a species that has not yet been described by scientists. Little is known about the biology of most species, but some are known to be thief ants, nesting alongside larger species of ants whose brood they prey upon.
