Figure 4


Intercolonial variation in relative proportion of fatty acids in washes of workers. Each bar represents the mean proportion of that acid (with standard error) of the total extracted from the bee. The numbers on the X axis represent colonies; corresponding bars for the different acids are from the same colony. N = 11 workers from colonies 1 and 2, 10 from colonies 3, 4 and 6, and 8 for colony 5. ANOVA results are given for each acid; the degrees of freedom for the ANOVAs are 5,54.
