 An experiment using a captive colony of "A. epedana" showed that even when the colony was starved the ant refused offered food alternatives.This specific behavior has also been documented in Dominican amber fossils dating back , with queens of the fossil species "Acropyga glaesaria" being found preserved with species of the extinct mealybug genus "Electromyrmococcus".Older trophobiotic associations have been suggested for the Eocene fossil ant species "Ctenobethylus goepperti" based on a Baltic amber fossil entombing thirteen "C. goepperti" workers intermingled with a number of aphids.
