Figure 2 in The impact of predation by the myrmecophagous spider Zodarion elegans (Araneae: Zodariidae) on the activity pattern of the Mediterranean harvester ant Messor wasmanni (Hymenoptera: Formicidae)

Figure 2 Flow diagram of nest entrance closure in response to prey capture by the spider Z. elegans. In total, four experiments were performed with an overall duration of 100 days (Trial 1: n = 20, Trial 2: n = 30, Trial 3: n = 30, Trial 4: n = 20, n(total) = 100). The capture of M. wasmanni workers by Z. elegans is necessary to prompt ants to end aboveground activity and close nest entrances. By contrast, the presence of spiders in the formicarium alone was not sufficient to prompt ants to close nest entrances after aboveground foraging activity ceased.
