Figure 3.

Effect plots with data points colour coded by nest ID and grey bands around the regression line depicting the 95% confidence interval. Wasps (n = 155) that exchanged solid food (ST) frequently are located closer to each other on the nest, and exchange of regurgitated food (SC) is also weakly positively correlated with spatial overlap. Dyadic aggressive interactions are not correlated with dyadic spatial overlap. GlmmTMB with β-binomial error family and nest ID as random effect (SC: estimate = 0.45, bootstrapped CI = 0.08–1, p = 0.004; ST: estimate = 1.68, bootstrapped CI = 0.33–2.02, p < 0.001).
