The picture to the right represents the achievement of one of my most cherished butterfly spotting goals: seeing my first Zebra Swallowtail in the wild. For some people, this gorgeous butterfly is a common sight, but for others, like me, this was a rare experience, one that I’ve only had a handful of times since this picture was taken. It’s not a perfect specimen, nor is it a great picture, but the thrill that came with spotting this little guy made that afternoon one to remember.
The Zebra Swallowtail (Eurytides marcellus) is Tennessee’s state butterfly and is found throughout the eastern U.S. The caterpillars of this species eat only one kind of plant – pawpaw (Asimona spp.), and as a result this butterfly is a common sight where there are large groves of this plant. In other areas, they are spotted only occasionally, but are hard to mistake when they do appear. No other butterfly in our part of the country has the distinct black and white markings and long tails, shown in better detail below.

Any butterfly gardener in the eastern U.S. can hope to see these butterflies drinking from nectar plants. For a better chance at drawing these beauties, you can try to establish some pawpaw in your yard. The problem is, pawpaw is slow-growing, difficult to start from seed, and even more difficult to transplant due to a very deep taproot (learn about my own experience with this plant here). However, butterfly lovers may still want to try it – learn more about the different species here to choose the one best suited to your region.

Hi Jill!
Congratulations! I always do a double-take when I see one of these, because they’re so striking. But I rarely see them- now I know why. Not a lot of pawpaw in my life!
I just read on two websites that this species ingests pollen that gets stuck to its proboscis, which helps it stay active for so long (March – August). But I’m not sure about the accuracy of the sources from which I read the information. Have you heard anything about this butterfly doing this?
Thanks!
Athena – You’re actually reading about a different butterfly with a similar name – the Zebra Longwing (Heliconius charithonia). This butterfly does indeed get additional sustenance from pollen, extending its lifespan by several months (pretty impressive, since most adult butterflies live only a few weeks). Check out this link for more info:

Thanks for reading!

Hi Jill,
Thanks for your response! It looks like the sources I was looking at were wrong. I just dug around some more and the Heliconius is the only one I can find in scientific literature that’s talked about as feeding on pollen as an adult. Thanks!
