myrmecophile

noun

1. An organism, especially an insect, that lives in close association with or shares a nest with a species of ant.

   “Ants are integral components of terrestrial ecosystems, owing to their manifold interactions with other organisms. They serve as seed dispersers for plants (myrmecochory), mutualists with sap-sucking insects (trophobionts), and hosts for a wide range of associate organisms (myrmecophiles) and act as both predator and prey.”
