We have seen this Beautiful Butterfly that looks very similar to the red spotted purple and the blue and black eastern swallowtail; twice this year weve seen it and were wondering what it was called until we came across this DG link today. It is hard to photograph, as the blue on it easily blurs if not completely still. We are honored this Beautiful thing comes to our gardens. Now we know of three different large black and blue butterflies here in NC!

In our region of Ohio/Indiana/Ky the Spicebush ST uses both the Spicebush and the Sassafras for oviposting.

We have both plants in our woods (along with some laurels) and around the second week in August we begin to see Spicebush ST regularly visiting our nectar garden. Their first springtime 'flight' occurs around mid-May in Ohio.

I am changing my Florida garden to Natives and one of the trees I transplanted this Spring was a young sassafras. In July I noticed that one of the leaves was curled, showing the silvery underside. Carefully, I peeled it open and found a brown caterpillar with large "eye" markings like that of a Spicebush Swallowtail. This was an early stage. In a few days the caterpillar was much larger and had the typical green and yellow coloration. Other leaves on the twig had parts of their edges missing; the caterpillar had been feeding when not hiding in its leaf nest. I did not see it turn to the clear yellow stage before pupating. One day it was gone. A week or so later I saw a black and silver butterfly in the same area; I'd like to think it was the former caterpillar.
