 "Ningaui yvonneae" shows a preference for smaller prey when presented with an alternative, with a higher net gain for the energy expended in consuming animals such as cockroaches, and opportunistic in their selection of Hymenoptera, Araneae and Coleoptera species.They are able to climb through dense spinifex and thin branches in search of prey, assisted by a partially prehensile tail, or forage around the vegetation on the ground.They reside during the day in the clumps of spinifex, species of the low, spiny and dense "Triodia" plants that dominate as hummocks, sometimes in association with other dense vegetation in semiarid mallee scrubland or heaths over sandy plains or dunes.
