Figure 1.

Consistency in aggression across two successive encounters (a) separated by various amounts of time or (b) across encounters with non-colonymates of two different colonies. The panels on the left shows the initial proportion of aggressive (black bars) versus non-aggressive interactions (grey bars). These focal workers were used in a second trial at either 15 min, 1 h, 1 day or one week after the first assay (top right panels) or in a second trial 15 min after the first assay against contestants of the same or a different colony (bottom right panels).
