Figure 1. Distribution, mimicry and phylogenetic relationships of sequenced taxa.
a Phylogenetic relationship of sequenced species and subspecies in the ‘melpomene- silvaniform clade’ of Heliconius. H. elevatus falls in the ‘silvaniform’ clade, but its colour pattern mimics melpomene-timareta clade taxa. b Geographic distribution of ‘postman’ and ‘rayed’ H. melpomene races studied here (blue, yellow and purple), and the entire distribution of H. melpomene (grey). The H. timareta races investigated have limited distributions indicated by arrows (red) and mimic sympatric races of H. melpomene. H. elevatus and the other silvaniform species are distributed widely across the Amazon basin (Supplementary Information 22).
