Fig. 3 in Strong phylogenetic constraint on transition metal incorporation in the mandibles of the hyper-diverse Hymenoptera (Insecta)

Fig. 3 Phylogenetic tree mapping the larval feeding resource (LFR) (0 = plant, 1 = animal (at least partially)) for each taxon analyzed in this study. The circle with a picture of a herbivorous larva (the bee Andrena agilissima (Andrenidae), feeding on a pollen ball) and of a carnivorous larva (the apoid wasp Sceliphron spirifex (Sphecidae), feeding on spiders) mark the ancestral state for Hymenoptera and for Apocrita, respectively. The histogram in the lower part of the figure shows the distribution of cases for a given rank of Zn, for species with either LFR type
