I found two eastern tiger swallowtail butterflies (Papilio glaucus) on a mulch bed at the Arboretum last week. They appeared to be basking in the sun. At times, both would shiver their wings. I assumed one of these butterflies was a male and the other female but, judging from the lack of blue chevrons on their hindwings, they both appear to be male.
