Because the butterfly lays its eggs exclusively on the milkweed plant, and the milkweed provides necessary food and habitat for the butterfly's larvae, it is a mutualistic relationship. There are no plant substitutes for where monarch butterflies can lay their eggs so there is a population dynamic connection between the butterfly and the milkweed plant as well. If the milkweed plants were to go extinct, then the monarch butterfly population would eventually decline because the butterfly would have nowhere to lay its eggs.
