(e) Ancestral host-plant associations

Ancestral host-plant associations across Philodoria were constructed using the ultrametric maximum clade credibility tree derived from the best BEAST analysis (based on MLE comparisons). Host-plant data were coded by family and are listed in table 1. Host range evolution was estimated using parsimony in Mesquite v. 3.31 [43].

Divergence time analysis results, with ages in millions of years with 95% highest posterior density range in parentheses. Part. = data partitioned or unpartitioned; 50/507 = 50- or 507-locus topology used as a constraint; BD/Yule = speciation process using birth–death or Yule prior; MLE score SS/PS = stepping-stone versus path sampling. The 11 analyses at the bottom did not reach convergence.
