Papilio troilus, the Spicebush swallowtail;
Volusia county, Florida (24 July 2020).
Here’s a quick iPhone snapshot of a Spicebush Swallowtail loitering around our backyard a few short years ago. We have a variety of Papilio species in this region, and I’d definitely like to see more of this specific species. Some awesome dark, dark blues going on there.
