Two-tailed Tiger Swallowtail: Centennial, Colorado, July 2024 — I went for a short walk around the neighborhood yesterday afternoon in the Denver heat to see if any birds were out and about. They weren’t, but I caught this Two-tailed Tiger Swallowtail visiting the Day Lilies in the entry-way plantings of one of the many housing developments that make up this part of Centennial. Perhaps the largest and most colorful of the western swallowtails, this one was diving deep in the lilies after nectar. It was very active and hard to keep in the frame.
