i) Phylogenies and species lists
We obtained two lists of 52 and 75 butterfly species within the
Heliconiini tribe from phylogenies used in Cicconardi et al. (2022) and
Kozak et al. (2015) respectively. For our primary analyses we use Kozak
et al.’s phylogeny (Figure 1A), as this incorporates a larger total
number of species. However, we also repeated all analyses using
Cicconardi et al.’s phylogeny (see Appendix for these results), as this
is based on a greater amount of molecular data, and has some minor
topological differences, but contains fewer species.
