Evolutionary models predict that parasite virulence (parasite-induced host mortality) can evolve as a consequence of natural
selection operating on between-host parasite transmission. Two major assumptions are that virulence and transmission are ge-
netically related and that the relative virulence and transmission of parasite genotypes remain similar across host genotypes. We
conducted a cross-infection experiment using monarch butterflies and their protozoan parasites from two populations in eastern
