Foraging did not differ between control (n = 23) and treatment colonies (n = 17). The large dots depict the mean ± standard error. The small dots represent the raw data points. We did not detect any significant difference between control and treatment colonies in (A) the maximum number of workers (ANOVA: χ2 = 2.05, p = 0.15) and (B) the time for the first worker to reach the food (ANOVA: χ2 = 0.11, p = 0.74)
