Tapinoma sessile is a species of ant that goes by the common names odorous house ant, stink ant, and coconut ant. Their colonies are polydomous (consist of multiple nests) and polygynous (contain multiple reproducing queens). Like many social insects, T. sessile employs complex foraging strategies, allocates food depending on environmental conditions, and engages in competition with other insect species. As with most other ants, T. sessile is eusocial. This is characterized by reproductive division of labor, cooperative care of the young, and overlapping generations.
