Adaptation to novel environments often results in unanticipated genomic responses to selection. Here, we illustrate how multifarious, correlational selection helps explain a counterintuitive pattern of genetic divergence between the recently derived apple- and ancestral hawthorn-infesting host races of Rhagoletis pomonella (Diptera: Tephritidae). The Apple host race terminate diapause and emerge as adults earlier in the season than the hawthorn host race to coincide with the earlier fruiting phenology of their apple hosts. However, alleles at...
