Protographium philolaus, the dark zebra swallowtail or dark kite-swallowtail, is a butterfly of the family Papilionidae. It is found from southern Texas to northern South America.

The wingspan is 90–95 mm. There are broad black bars on the upper surface of the forewings of the males. Females are similar, although some are almost completely black. Both sexes have long tails. Adults feed on flower nectar.

"Antenna black; the 7. pale green band of the forewing only represented by a spot; hindwing with 2 red spots posteriorly; on the under surface the red line of the hindwing edged with black at both sides, undulate anteriorly. Scent-scales of the male short, broad, irregular, produced in a number of filaments. The female is in 2 forms: female f. philolaus Boisd. similar to the male, the underside paler, female f. niger Eimer (nigrescens Eimer; felicis Fruhst.) the pale green bands of the membrane of the wings scaled with black, the wings therefore black with slight traces of the bands."

Biology

The butterfly is found in low situations, often resting in crowds on the sand at the edge of rivers. The larvae feed on Annonaceae species.
