Another sighting on the butterfly bush, this time by me. This is a Zebra Swallowtail butterfly.
I don't think these are as common as Tiger Swallowtails, large yellow marked butterflies. But the Audubon Guide notes that Zebra Swallowtails "are the most abundant regular North American representative of the kite swallowtails, named for their triangular wings and long sharp tails. Despite a large range, the zebra occurs only near pawpaw trees or its relatives." The host for Tiger Swallowtails are deciduous trees.
We must have pawpaw trees in the nearby woods. "Picking up pawpaws, putting 'em in our pockets..." Catchy tune!
