Relationships between ants and other organisms are numerous -
Ant/Ant: Some species of ants are extreme in their dependence
upon other ant species. For example, the ant Tuleutomyrmex
schneidere spends almost its entire life riding on the backs of
host ant species. They seem to contribute nothing to the hosts,
but are tolerated and even fed. Slavemaker ants (Formica
subintegra, for example) steal brood from other colonies and
return the brood to develop and serve the Slavemaker colony. The
slaves are absolutely dependent in that if they don't work, they
don't get fed. Other ants work together as with the
Crematogaster limata parabiotica and Monacis debilis. These ants
have their nests close together and share the same foraging
trails. Camponotus has also been seen giving food to the Monacis
workers. - Ant/Other Insect: These relationships are many and
diverse, ranging from commensual to parasitic. Aphids and ants
have many species relationships where both the ants and aphids
benefit (mutualism). Aphids secrete
