 The workers search for prey in piles of leaves, killing small arthropods including "Drosophila" flies, microlepidopterans and spiderlings.Prey items are usually less than in size, and workers grab them using their mandibles and forelegs, then kill them with their sting.Workers also feed on sweet substances such as honeydew secreted by scale insects and other Hemiptera; one worker alone may feed on these sources for 30 minutes.
