These butterflies lay their eggs in pine trees, and the caterpillars eat the needles.
I don't know the identification for this one, some type of wood nymph, I'd guess? Let me know. See it with wings open below....

This very large butterfly visited a hanging flower basket outside my office window. I scrambled to get a picture and had to take it through the screen. It's a Western Tiger Swallowtail. I've seen this type before feeding on zinnias on the yard.
Another plant I use for decorative purposes, also for cooking, and for attracting pollinators and butterflies. This is creeping thyme. It even works well in hanging baskets and planters, and it comes back every year.
