(A) Discovery time (d) and assessment time (a) for informed and naïve colonies (n = 16). Bar lengths and whiskers represent means and standard errors, respectively. General linear mixed model (GLMM), effect of treatment, discovery time: χ2 = 1.31, df = 1, p = 0.25 (ns); assessment time: χ2 = 25.03, df = 1, p < 0.0001 (*). (B) First recruitment decisions by first discoverers in informed and naïve colonies (respectively; ∅: no recruitment; TR: tandem running; T: transport). The distribution of first recruitment decisions was compared between the two treatments using Fisher-Freeman-Halton’s exact test (p = 0.023). The sample size differs between the two treatments (informed: n = 16; naïve: n = 22) because when the first discoverer did not initiate recruitment within 90 min (∅), the new nest was replaced with another fresh nest, and the next worker that discovered it was considered first discoverer (see Methods for details).
