Biology
Tapinoma simrothi in Saudi Arabia was observed nesting in a decaying carpet, among roots of graminae plants and attending unidentified mealybugs, and also coexisting with Solenopsis saudiensis (Sharaf and Aldawood 2011).

Karami-jamour et al (2018) studied interactions between this ant and the aphid Aphis gossypii. Tapinoma simrothi tends this aphid and potentially protects it from predators. Laboratory microcosm experiments with plants, ants, aphids and two aphid predators (Chrysoperla carnea Stephens, green lacewing and Coccinellia septempunctata Mulsant, ladybird/ladybug) suggested T. simrothi can decrease predation of the aphid.
