The effect of injecting homogenates of different insects on the melanization of oil droplets. The bar chart shows the proportion of oil droplets that were melanized with 95% binomial confidence intervals. The red line is the rate at which oil droplets were melanized without any insect homogenate (N = 241). The red bars are parasitoids of D. melanogaster. The tree [35] is colored according to estimated melanization rates from a phylogenetic mixed model in which the parasitoid status was included as a fixed effect. Sample sizes are given beside the bars. The silhouettes represent different insect orders (from top to bottom: Diptera, Coleoptera, Lepidoptera, Hymenoptera, Orthoptera, Dermaptera, Hemiptera, Odonata)
