Listing common butterflies for our area, different attractant plants, a list of invasive plants, and some other good info links.
If you have a butterfly 'fact sheet' from your state's extension (or similar) it may be helpful to others to post it.
I noticed on the Ohio 'fact sheet' it listed several common butterfly plants that I had no idea were considered 'invasives'. I didn't know that the 'daylily' was an 'invasive', for instance. That surprised me.
