released what I thought was a spiced bush swallowtain today but looking at photos online, I cannot tell if it was a spiced bush or an eastern black swallowtail. Seeing how I am located in Northern VA, I suspect that it was an eastern black ST BF. But how does one know for sure? and how does one discern male and female of each species? Thanks!
