Rate of antennation with the queen (per scan per bee), task allocation (percentage of scans) for all behavioural tasks recorded, and presence on the brood (percentage of scans) for resident and introduced bees in the foreign condition. Rare activities (representing <1% of total acts) were excluded from the analysis (exact permutation tests). Data are presented as mean ± standard error.
