I also have milkweed swamp common and butterfly weed A.tuberosa

If you have not tried this site yet it may be helpful. They have native recommendations by state and you can narrow it down by your growing conditions and what size plants you can accommodate. There isn't a separate filter for butterfly plants, but when you click on each individual plant it says what wildlife it is good for and lists some species the plant is a larval host for too. They also have something similar on the Prairie Moon Nursery site.
