Ancestral character state parsimony reconstruction of host species (left) and geographic region (right) on the BEAST phylogeny. Character states summarize records of all specimens identified by mtCOI sequence, with all states represented by > 5% of total specimens shown on the tips. Inferred ancestral states for host tissue are shown by colored dots on branches, with shifts to feeding on seeds (tan) or specialization on female flowers (pink) shown by colored arrows (several lineages feeding on both flower sexes, with > 5% of specimens on male flowers, are not marked). The dashed lines at 3 Ma divide each tree into older and younger splits, corresponding to the analysis shown in Fig. 4
