Wing span: 6.4-10.4 cm.
Flight time: Two broods, one from mid-April through June, with a partial second brood in August.
Status: A breeding resident in the extreme south; a stray elsewhere.
Distinguishing features: This striking butterfly is the only Iowa swallowtail that is black and white striped. It has tails to 2.5 cm., with a wingspread of 6.4-10.4 cm.
Distribution and habitat: This species is very rare in Iowa and restricted to mesic, lowland forests. While the only known breeding colony occurs in Waubonsie State Park (adults are seen in flight there during most years), others should be sought in the southern tier of counties.
Natural History: The larval host in Iowa is papaw (Asimina triloba), which is itself quite uncommon in the state. While this species is double-brooded in Iowa, only a single specimen of the larger, darker, long-tailed summer brood has been reported.
