Feeding on hickory.

Walnut Sphinx (Cressonia juglandis) - Amorpha juglandis
This species feeds on Hickory so could be a good start - Northern Prairie
Strange, but npwrc has one genus name under the adults and a different genus for the caterpillar.

By the way, we typed Sphingidae as the Lepidoptera family and Carya as the plant genus into the caterpillar host plant database, Host plant , restricted the search to USA, and this was the only species to pop up!! Try it, you'll like it.

I think the Balabans have it
Check this:
Caterpillars of Eastern Forests - Walnut Sphinx

Bill Oehlke's Page for this species has a good caterpillar image as well. He notes two genus names, Amorpha and Cressonia and notes a third one, Laothoe juglandis which may be a subspecies. Confusing!

Let's stick with Arnett (1), who uses Laothoe and notes that Cressonia is a synonym. That also generates the most google search hits.

Very useful
I've added it to the guide.

Very cool resource!
When I went to it, I realized I had discovered it and saved the link some time ago, but forgot about it. Thanks for the heads up and reminder.
