Figure 1.

Variation in the number of eggs + larvae among different colony sizes. Brood numbers were 1-truncated (colonies lacking any eggs or larvae were excluded). A Kruskal Wallis non-parametric test indicated a significant effect of the number of adult females on the number of eggs and larvae present within nests (χ23 = 12.145, P = 0.007). The blue line displays the proportion of nests containing brood for different colony sizes.
