**p<0.01; n.s. = not significant, p>0.05 (a) Experiment 5: Digging activity with brood only (Analysis of colony effects: ANOVA; brood; F = 1.91; p = 0.19; n = 5; no brood; F = 0.25; p = 0.79; n = 5; n.s.; no colony effects found) (b) Experiment 6: Digging activity with brood and fungus (Analysis of colony effects: ANOVA; brood and fungus; F = 0.64; p = 0.54; n = 5; fungus; F = 0.22; p = 0.8; n = 5; n.s.; no colony effects found).
