dark meadow katydid Conocephalus? - Conocephalus saltans -
Warsaw, Hancock County, Illinois, USA August 14, 2016
I saw this boy on a degraded sand prairie / levee on a grass next to what I think was a Conocephalus strictus (green). I thought perhaps this was just a strange color form of that species. Then I photographed the female a few feet away. Now I'm definitely unsure.
