Eastern Tiger Swallowtail
Thanks so much for helping with the ID of this one. Glad you mentioned the osmeteria. I forgot that it did put out a strong scent when I first handled it. I don't have any background with insects, but thought this one was quite unusual. It looked so strange my mother didn't think the image I sent her was for real! I take it they are fairly common in Iowa??

Eastern Tiger Swallowtail
See guide and compare below. Those tentacles you saw are scent-producing structures called osmeteria that they use to scare off predators - all the swallowtail caterpillars have them.
