Fig 1. A schematic of the plaster nests in which the ants were housed.

Fig 1

Access to the nest was via a 5mm diameter hole in the lid of the nest, at the centre of the nest entrance (NE/00) cavity. The locations of faecal patches (= toilets) were defined by their square type (C = corner, S = side, M = middle, E = cavity entrance, NE = nest entrance), and by an XY coordinate, with the nest entrance as an origin. Cavities are denoted TL, TR, BL, BR (Top left, top right, etc.) according to their location relative to the side of the nest facing away from the nearest wall. The plaster nest was placed to one side of a square foraging box. The black dot represents the side of the nest facing away from the nearest wall of the foraging box
