Frequency distribution of aggression among non-reproductive P. punctata workers over all colonies (n = 8) during (a) colony fusion and (b) enemy introduction. Observed distributions were significantly more skewed than expected from random sharing of aggression (χ2-test, assuming a Poisson distribution, λ = average no. of aggressive acts per worker: (a) χ2 = 707.81; λ = 3.2; (b) χ2 = 89.94; λ = 19.53; p < 0.001 in both cases).
