25The founding individuals of a new group or lineage are uniquely poised to have long-lasting 26 effects on their descendants. Here we explore how the behavioural traits of new 27 foundresses influence their task allocation strategies and the downstream collective 28 behaviour of their colonies. We collected individual paper wasp (Polistes metricus) queens 29 from the wild, and measured their boldness, aggressiveness, exploration, activity, and time 30 budgets in the laboratory. We then provided queens with food and nest materials and 31 waited for their workers to eclose. We subsequently tested for links between queen 32 behavioural traits (e.g., boldness, aggressiveness) and the collective aggressiveness of their 33 colonies, as estimated by the number of workers that responded to and stung a model 34 predator. We found that bolder queens (i.e., queens that were less likely to leave their nests 35 after repeated exposure to an agonistic stimulus) spent more time nest guarding, reared 36 more workers, and produced groups that were less responsive to a model predator. Thus, 37 there appears to be parent-offspring, or queen-worker, resemblance in the degree to which 38 individuals remain on their nests in different social contexts (solitary queen vs. queen + her 39 worker group). To our knowledge this represents the first study to explicitly test for links 40 between individual variation in foundress behavior, worker production, and inter-colony 41 collective behaviour; the results highlight the possibility that cross-contextual and trans-42 generational behavioural links could be a reasonably common and potentially important 43 phenomenon in complex societies. 44 45 46
