I am much more a photographer than an expert on butterflies, and just became aware of the Spicebush variety. I have been calling all the ones that I have photographed locally Black Sallowtails. After looking at the various photos and info on this site, I am still confused. Some of the photos on my web site
look like Spicebush, but also look like some of the Black Swallowtail photos I see on bugguide.net. I have often seen Black Swallowtail caterpillars here, but have never seen a Spicebush caterpillar. I would appreciate any opinions on the five photos in question I have on my web site as to which of these two species they are.
