Very cool! That is the larva of one of our big native Hawk moths. The blue horn makes me think it's the caterpillar of the Blind-eyed sphinx moth (Paonias excaecatus), which feeds on oaks and other trees and shrubs. None of the sphinxes with larvae like this are pests. And they mature into big beautiful moths, too. Thanks for being on the lookout!
