The zebra swallowtail butterfly (Eurytides marcellus) is one of six species of swallowtails found in Iowa. While you are much more likely to find them in the southeastern part of the United States, they are occasionally spotted in Iowa, particularly in years when there are higher than normal populations in the southeast. Sightings in Iowa are typically in the southern part of the state but, this year I have heard a couple of accounts of them being spotted in central Iowa. It is very likely zebra swallowtails are flying around other parts of the state, but those sightings are not being reported anywhere. If you happen to see an individual and would like to submit your sighting, you can do so at www.butterfliesandmoths.org.
Pawpaw is hardy in Iowa and can do well across most of the state. By planting a pawpaw in your yard you increase the odds that one day you might just see a zebra swallowtail. The zebra swallowtail is an amazing species to see in flight, if you are lucky enough to come across one.
The zebra swallowtail butterfly is aptly named with its black and white stripes.
