1. An herbivore’s life-history strategy, including optimization of resource use, is constrained by its evolutionary history and ecological factors varying across the landscape.2. We asked if related and co-distributed herbivore species maintain consistency of host preference and oviposition behaviours along the species’ range. We surveyed two putative species of milkweed stem weevils, Rhyssomatus lineaticollis and R. annectens, which co-occur alongside their hosts, Asclepias syriaca and A. incarnata. 3. We confirmed the two species status of weevils, supported by differences in morphology and a bilocus gene phylogeny. Furthermore, we found that species divergence recapitulated the weevils current host plant use. 4. We found oviposition variation within and between species. R. annectens poked the stem haphazardly or girdled it before oviposition. Meanwhile, R. lineaticollis primarily trenched stems in the north, but poked or girdled in the south. Variation in oviposition patterns could be a response to variation in host plant defenses. 5. In nature, weevils strictly oviposited on their respective host plants, while in
