Recent work on the fine scale habitat requirements of&nbsp;<em>C. aureus</em>&nbsp;provided the opportunity to expand the search for additional suitable habitats for this species in the Gauteng Province, using GIS and current distribution databases. A topographical base map and overlays of food plant (<em>Clutia pulchella</em>), host cocktail ant (<em>Crematogaster liengmei</em>) distributions and geology (Ventersdorp Supergroup) were used to determine possible additional sites suitable for&nbsp;<em>C. aureus</em>. Eight potentially suitable sites were identified. Four of these sites where transformed by mining activities and thus excluded. One of the four remaining sites was deemed suitable for&nbsp;<em>C. aureus</em>&nbsp;as both the food plant&nbsp;<em>(C. pulchella)</em>&nbsp;and the host ant&nbsp;<em>(C. liengmei)&nbsp;</em>were present.&nbsp;<em>C. aureus</em>&nbsp;was not recorded at any of the other sites surveyed probably due to season of site visits (winter).</p> Chrysoritis aureus, habitat, Clutia pulchella, Crematogaster liengmei Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2019-JAPS-333
