This is an Eastern Tiger Swallowtail. The poor thing has definitely been through some trauma, but it can still fly. I thought it was being surprisingly friendly, willing to pose for me with my intrusive iPhone 11. Now I realize that it’s probably just a bit worn out. It’s probably a bit more difficult for it to get about as compared to one of his own with wings that are completely intact. By this time of year, I start to see many butterflies with wings that have seen better days. It was small for an adult, but perhaps that’s to be expected. It may not be able to harvest as much nectar as a healthy Eastern Tiger.
