I followed this from caterpillar to chrysalis to moth. I wish I had taken some snaps of the caterpillar but I thought it might be a Palamedes Swallowtail (though it had a single horn that the swallowtail doesn’t). I was pretty surprised at what came out. I think that I have identified it as a Tersa Sphinx. I live in northeast Florida.
