Permutational multivariate analysis of variance using Sørensen dissimilarity matrix of presence or absence of prey species in each sample. Terms were added sequentially to the model meaning that the significance of each term is evaluated against the background of terms above it. Predator body size was measured as the average hind wing length of each individual, with factor Predator referring to the species of dragonfly (three levels)

Predictor	SS	F	R 2	p

Predator species	1.27	1.39	0.04	.076
Sex	0.53	1.19	0.02	.289
