Proportions (mean ± SD) of hatched larvae from queen-laid and worker-laid male eggs in the three test colonies. There was no significant difference between the test colonies in the proportion of hatched larvae. Significantly more larvae hatched from queen-laid eggs (n = 581) than from worker-laid eggs (n = 1,317; χ2 = 122.94, df = 2, P < 0.001).
