The deep notch in the pronotum is the give-away. Only other species similar at this age and in that area would be Sparagemon collare, but the crest generally isn't quite so high this far north, and the coloration is usually speckled more, among other minor differences (if you could see the hind tibiae, they are orange to red in S. collare and dull earth-toned in D. carolina). The thing that bothers me, is I see a hint of orange, and I can't tell if it's part of the grasshopper?
