Description
The Zebra Swallowtail has a wingspan of 6.4 to 10.4 cm (2.5 to 4.1 in). The triangular wings are white to greenish-white with black longitudinal stripes. A pair of swordlike tails extend from the hind wings. The inner margin of the hind wing has two blue spots on the corner and a red spot near the body. A red stripe runs along the middle of the ventral hind wing. P. marcellus has two seasonal forms, one occurring in the spring and the other in the summer. Spring forms are smaller, more white, and have short, black tails with white tips. Summer forms are larger, have broader black stripes, and longer, black tails with white edges.

“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
