The next three pics are not that great, but I'm very interested to find out if you think they are Black Swallowtails since I don't think I've seen those before. They were mating in flight over a field. When I first saw them I thought it was a Polydamas mating with a Pipevine since one was black with yellow spots on top and one clearly had blue on top and was also black. That's why I think it might be the Black Swallowtail. They come in both color right?
