All I remember noticing so far in our yard (Maryland) are cabbage whites, a few sulphurs (not sure which ones), skippers, and lots of tiger swallowtails. There was one lovely black-colored swallowtail but it may have been a melanistic female tiger swallowtail (the mimic the pipevine swallowtails which are poisonous.) Every year the tiger swallowtails practically patrol the butterfly bushes to keep off other large butterflies. Sigh....
