I think first two photo's are of Black Swallowtail (Papilio polyxenes) and last is of Pipevine Swallowtail (Battus philenor) but I could be mistaken. I live in the Northern Chihuahuan Desert, in Southern Texas. There is great biodiversity here but things like these butterfly's are in a localized bio habitats, and usually involve hours of walking. The quality of some of the some of the photo's I have seen here is far beyond my current skill level but it gives me something to strive for.
